Challenges were present as participation increased. Despite the challenges posed by enduring gender stereotypes and sexual harassment, women continued to seek careers in the rafting industry. In 2016, the management of Grand Canyon National Park halted the operations of its River District, which oversaw regulatory adherence and provided emergency assistance, as part of an effort to tackle the persistent problem of sexual harassment faced by female river guides at the hands of male rangers. Sevigny highlights the extent to which these perspectives had taken root, as evidenced by reporters who inquired if Jotter intended to purchase headwear that better suited a woman following her 1938 expedition. Female guides continued to demonstrate their skill, courage, and determination among the community of river navigators.

The botanical specimens and academic contributions of Clover and Jotter were instrumental in understanding the ecological changes occurring in the Grand Canyon.

Sevigny highlights the lasting significance of the plant research conducted by Clover and Jotter, whose work remains pertinent well beyond the end of their expedition. In the 1990s, the construction of the dam in Glen Canyon raised substantial ecological concerns, leading researchers to investigate historical documents and early studies on plant life to gain a crucial comprehension. Jotter was invited to participate in the 1994 expedition that paid tribute to the seasoned voyagers who had previously traversed the river's courses. The Bureau of Reclamation assembled a team of experienced rafters for an expedition to exchange insights on the river's transformation and to assist in developing strategies for the restoration of the canyon's natural environment before the dam's closure.

Cutter's participation with experienced professionals throughout the expedition underscores the significance of historical knowledge in understanding environmental transformations. Her unique understanding of the Colorado River's condition before the construction of the dam enhanced the scientific knowledge regarding the impact of water level changes, which were linked to power production, on the native plant and animal life. In her 1938 compilation, she documented the proliferation of the invasive tamarisk tree, which later guided strategies for managing its expansion. Her comprehension of the river's ebb and flow was instrumental in planning regulated water releases to reestablish the Grand Canyon's natural balance.

Practical Tips

• You can honor the legacy of pioneering women in botany by creating a digital herbarium. Start by photographing local plant species during your walks or hikes, then upload and tag them on a citizen science platform like iNaturalist. This contributes to the collective knowledge of plant biodiversity and continues the tradition of exploration and documentation started by female botanists.
• Encourage young girls' interest in botany and exploration by gifting plant-growing kits. These kits can be simple, with seeds, soil, and instructions for growing a plant at home. By nurturing a plant from seed to maturity, girls can engage with science hands-on, breaking down the stereotype that scientific exploration is not for them.
• Start a book club focused on literature by and about women in science. Choose books that highlight the contributions of female scientists, their challenges, and their triumphs. This can be a way to educate yourself and others about the historical and ongoing role of women in scientific fields, fostering a greater appreciation and understanding of their work.

The struggle emerges from the need to protect natural surroundings while also striving to utilize the resources offered by the river that flows through Colorado.

In the early 20th century, attention shifted toward augmenting the worth of the Colorado River through the construction of dams, the development of water diversion infrastructures, and the encouragement of expansion in nearby areas.

Engineers and politicians embarked on an ambitious project to establish control through the building of multiple dams aimed at harnessing and regulating the river's water resources.

The author examines the transformation of perspectives regarding the utilization of the Colorado River's energy for human advantage throughout the 20th century. At the turn of the 20th century, despite warnings from the explorer who cautioned about the limitations of arid areas, there was a dominant desire to transform the desolate landscape into a sprawling haven. Visionaries designed an intricate network of dams, reservoirs, and canals with the goal of distributing water to both city dwellers and countryside, thereby fulfilling the dream of extending throughout the continents. In 1922, the seven states traversed by the Colorado River formed a collective legal pact, the Colorado River Compact, to oversee and allocate the waterway's resources. The Compact assigned entitlements to a quantity of water that exceeded the river's true flow due to an overly optimistic assessment of its supply, rather than addressing the core issue of water scarcity in the arid West.

Eugene La Rue and his team of engineers led the initiative to build obstructions over the Colorado River, meticulously mapping the canyon areas to pinpoint optimal sites for dam construction, and devised a strategy for interconnected reservoirs to regulate the flow of the river. Despite mounting evidence suggesting otherwise, the conviction that technological advancements could surmount the constraints imposed by nature fueled these initiatives. A passionate supporter conveyed through poetry in an Arizona periodical: "Certainly, although the landscape is arid, it thrives with the support of water reservoirs, irrigation networks, and aqueducts!"

Conflicts frequently emerged among nascent collectives committed to safeguarding the river's intrinsic characteristics.

Sevigny highlights the tension between proponents of dam construction and those who opposed such initiatives out of concern for environmental and scenic consequences. People with a deep connection to the Colorado River's wild beauty, especially those who had journeyed along its waters, raised alarms about the increasingly scarce segments of the river that remained free-flowing. They viewed the rapidly moving rivers and the unique natural habitats within the steep canyons as intrinsically valuable, more than just resources for exploitation.

The creation of Yellowstone, as well as places like Yosemite, marked a growing appreciation for the splendor of the natural world, but often prioritized drawing tourists over preserving the untouched condition of the environments. George Meléndez Wright, a biologist working for the agency responsible for managing national parks, opposed these methods, promoting the conservation of parks' natural ecosystems instead of focusing exclusively on the amusement of visitors. Wright's innovative ideas, however, remained unnoticed during his lifetime. The construction of Glen Canyon Dam continued the trend of controlling and managing the Colorado River's currents.

The construction of major dams like Glen Canyon Dam significantly altered the Colorado River's ecology and human relationship to the landscape

The building of obstructions on the river led to changes in its original path, endangering the native plant and animal species by interfering with their traditional patterns of existence.

The construction of the Glen Canyon Dam has been meticulously studied by the author, revealing profound alterations to the ecosystem of the Colorado River. The dam's construction, finished in 1963, fully harnessed and managed the flow of the river. The creation of this massive dam resulted in the formation of Lake Powell, now the United States' second-largest reservoir, submerging a vast region that included the intricate network of subsidiary gorges in Glen Canyon. The dam's creation tamed the previously wild and unpredictable river, transforming it into a controlled channel and thus altering the age-old cycle of floods and droughts that had shaped the canyonlands for millennia.

The change in water currents initiated a cascade of effects on the native plant and animal populations. The annual spring floods, essential for removing built-up silt and nurturing habitats conducive to the growth of various plant species, no longer occurred, leading to a decline in these important tree types. The continuous release of cold water from the reservoir favored invasive species like rainbow trout, which subsequently preyed upon the indigenous fish populations, leading to their decline. The dam's construction caused sediment to accumulate upstream, consequently leading to more transparent water flowing downstream, while simultaneously diminishing the ecosystem's diversity. Sevigny illustrates the change as securing a reliable supply of water for city and farm use via hydroelectric power, yet concurrently, it adversely affected the ecological diversity and resilience of the waterway.

The building of dams along the Colorado River resulted in the inundation of significant cultural and archaeological sites, which in turn disrupted the connection that Indigenous peoples maintained with these lands.

Sevigny highlights the clear consequences and the more nuanced, equally destructive effects that the building of barriers across the Colorado River has caused, which encompasses the degradation of cultural legacy and the disruption of the profound connections that Indigenous groups maintain with the territory. The rising waters of Lake Powell engulfed ancient cliff residences of the Ancestral Puebloans, as well as areas with petroglyphs and territories revered by the Hopi, Navajo, and Havasupai peoples. The vanishing of these sites, often overlooked by archaeologists, represents an irrevocable loss of cultural legacy and a profound interruption in the enduring traditions of native communities.

The Havasupai had to leave behind their ancestral territories, an event deeply rooted in intense grief. In the 1800s, the Havasupai were compelled by the U.S. government to reside on a small reservation within the expansive Grand Canyon, restricting their access to the plateau regions where they traditionally lived during the winter months. The creation of Grand Canyon National Park in 1919 encroached on their territory, and the development resulting in the submersion caused by the Glen Canyon Dam flooded parts of their reservation, transforming their traditional lifestyle. The writer acknowledges that while the ambition to control the Colorado River is often celebrated as a triumph of human ingenuity, this endeavor has simultaneously inflicted significant damage upon Indigenous populations who have lived in harmony with the river's undisturbed course for generations.

The administration of the Colorado River increasingly reflects contemporary environmental science advancements and societal shifts that support a strategy emphasizing ecological balance and enduring sustainability.

Scientists and activists have championed the implementation of controlled water discharge trials and additional techniques to reinstate the river's inherent rhythms.

Sevigny documents the development of a new perspective on the Colorado River, influenced by advancements in ecological research and a growing awareness of the ecological consequences associated with dam building. As the 20th century came to an end, there was a notable shift in viewpoint, moving away from dominating the river towards an increased focus on understanding and restoring the river's natural ecological processes, which had been modified due to human interference. Scientists from the U.S. Geological Survey, in collaboration with experts from multiple institutions, began a study to determine the effects of the Glen Canyon Dam on the ecosystem of the Grand Canyon, observing the decrease in native species and the disruption of the natural ecological cycles.

Scientists and activists, equipped with fresh insights, championed a pioneering strategy for the stewardship of the river that considered its environmental requirements. Robert Webb, a scientist with the USGS renowned for his comprehensive research into the historical changes of the Grand Canyon, was a staunch advocate for initiatives aimed at restoring elements of the river's initial flow patterns. He argued that by manipulating the dam at Glen Canyon to control substantial releases of water, it would be possible to mimic the conditions of natural spring floods, thereby aiding in the replenishment of sandbars and improving the environment for native plants and animals. As environmental concerns related to the dam's impact increased, the strategy that was initially met with resistance by the dam's administrators, due to concerns over decreased hydropower production, slowly began to gain acceptance.

Debates persist regarding the destiny of the Colorado River, underscoring the delicate equilibrium necessary to harmonize human endeavors with the preservation of the natural world.

The author explores the complex and often conflicting viewpoints on water resource use in the dry western regions, focusing specifically on how the Colorado River's flow is controlled and its future determined. The river is essential for the water requirements of cities and farms throughout the Southwest, yet the growing number of inhabitants is exerting strain on its limited supplies. Climate change worsens the scenario by forecasting extended periods of dry weather coupled with increasing temperatures.

In this case, managing the river's resources requires finding an equilibrium between human needs and the preservation of a vibrant ecosystem. Sevigny underscores the challenge of balancing the river's ecological rejuvenation with the critical duty of providing water to millions of people. The experimental augmentation of water flow from Glen Canyon Dam has shown promise in rebuilding sandbanks, though it has not fully mitigated the dam's ecological impacts. Efforts to manage invasive species like tamarisk are contentious, with some arguing that these plants might offer ecological advantages for certain species, yet there is worry about their effects on native plant life. The future of the river as it meanders through Colorado is dependent on our capacity to balance human needs with a deep respect for the natural systems that sustain our lives.

Other Perspectives

• The Colorado River Compact's overestimation of the river's supply could be seen as a product of the times and the limited hydrological data available, rather than a failure of the agreement itself.
• The construction of dams and water diversion projects has provided significant benefits, including hydroelectric power, flood control, and a reliable water supply for agriculture and urban areas, which might justify their environmental impacts to some extent.
• While the Glen Canyon Dam has had ecological impacts, it also created recreational opportunities and economic benefits that some argue are valuable.
• The inundation of cultural and archaeological sites, while tragic, is a complex issue where the benefits of water resource development are weighed against the preservation of heritage, and some might argue that not all such sites can be preserved.
• The focus on ecological balance and sustainability in managing the Colorado River might overlook the immediate and practical needs of human populations that rely on the river for their water supply.
• Controlled water discharge trials to restore the river's natural rhythms may not be feasible or sufficient to address the extensive alterations to the ecosystem and could potentially disrupt water supply reliability.
• Debates on balancing human needs with preserving the ecosystem sometimes do not fully consider the economic realities and the necessity of water resources for human survival and development in arid regions.
• The challenges posed by climate change to the Colorado River's ecosystem and water supply might require more aggressive management strategies than those currently advocated by scientists and activists.

The enduring scientific findings and contributions that arose have their origins in the expedition led by Clover and Jotter in 1938.

During their 1938 expedition, Clover and Jotter conducted botanical studies that resulted in groundbreaking discoveries about the canyon's flora.

Their meticulous records and comprehensive observations provided an unparalleled scientific account of the natural environments along the Colorado River.

The author highlights the groundbreaking botanical research undertaken by Clover and Jotter on their expedition in 1938. Prior to the work of these trailblazing researchers, the path that follows the Colorado River through the canyonlands, while known to geologists and thrill-seekers, had not been comprehensively cataloged in terms of its plant life. They commenced their journey at the Green River and brought it to an end at Lake Mead, diligently collecting specimens from each site they explored, equipped with botanical presses and a methodical strategy for recording their findings. Their journals offer comprehensive descriptions of the canyon's varied ecosystems, emphasizing the subtle shifts in vegetation noted as they traveled from the upper reaches of the Colorado River into the vast depths of the Grand Canyon.

Their research made a substantial impact on the field of botany, which is demonstrated by the inclusion of their work titled "Floristic Studies in the Canyon of the Colorado and Tributaries" in the 1944 issue of the American Midland Naturalist. The research built upon their earlier work on cacti from 1941, providing a comprehensive catalog of more than 400 varieties of flora identified along the course of the river. Sevigny noted the documentation as being unparalleled in its thoroughness regarding the canyon's flora, highlighting their steadfast dedication and determination. The publication laid the groundwork for future ecological studies by providing a methodology for scientists to observe the ecological changes that occurred after the erection of Glen Canyon Dam, including the proliferation of invasive species.

Clover and Jotter encountered a range of cacti species found only in the Grand Canyon region.

The exploratory expeditions undertaken by Clover and Jotter led to the identification of numerous previously undocumented cactus species, as well as the creation of a comprehensive catalog of plant life. The canyon was a haven for a wide array of living organisms, with its many hidden recesses playing host to these spiky marvels. The flora, characterized by its diminutive blossoms and curved spines, was identified as a unique species due to its notable characteristics. The species Opuntia longiareolata is distinguished by its extended pads and a hue of green with a yellowish tint, typical traits of cacti.

The author highlights the keen observational skills and meticulous approach to scientific inquiry that were evident in the results produced by Clover and Jotter. They braved treacherous terrains to collect those specimens, diligently recording their observations while withstanding the rigors of an arduous journey adjacent to the waterway. The herbarium at the University of Michigan, along with the Smithsonian Institution, enhanced their archival holdings by including these newly discovered species and their plant specimens, thereby supporting ongoing studies into the evolutionary development and distribution patterns of cacti.

The plant specimens and records gathered throughout the expedition were crucial in understanding the lasting environmental changes in the Grand Canyon.

The environmental standards established through the work of Clover and Jotter provided an essential point of comparison for scientists studying the impacts of building dams, introducing species not originally from the area, and other human-induced changes to ecosystems.

Sevigny highlights the significance of Clover and Jotter's 1938 expedition, emphasizing that its impact went further than the scientific findings of the time, playing a vital role in enhancing our understanding of the widespread ecological changes occurring across the vast Colorado Plateau. They documented the diverse species inhabiting the riverbanks during a period of ecological balance, just before the impact of widespread dam building became evident, finishing their studies shortly before the construction of the Hoover Dam was finalized. The creation of a reference point before building the dam became important for scientists dealing with the consequences after the 1963 erection of a blockade through Glen Canyon, which markedly altered the flow of the river, the movement of sediment, and the surrounding plant life.

Decades later, scientists like Robert Webb leveraged the detailed botanical records and thorough observations gathered by Clover and Jotter to monitor the invasion of exotic species and observe the reduction in numbers of native cottonwood and willow trees. Investigations into the river's ecological state prior to and following the dam's erection revealed considerable alterations resulting from human interventions.

Years after her initial journey, Jotter had the chance to personally witness the changes the Colorado River experienced during a subsequent expedition, which was a voyage for those experienced with the river, allowing her to evaluate the river's state before and after the dam was built.

In 1994, at the age of 80, Lois Jotter Cutter had the extraordinary chance to return to the Colorado River with a U.S. Geological Survey team, which aimed to investigate the enduring ecological effects resulting from the construction of Glen Canyon Dam. The voyage, dubbed the "Old Timers Trip," brought together those who had once braved the wild rapids of the Grand Canyon before the construction of the dam, providing a unique perspective on the river's transformation. Jotter Cutter, the only member of the 1938 plant study expedition, provided essential insights into the changes that occurred over the subsequent fifty years, based on her firsthand observations.

Sevigny highlights Jotter Cutter's pivotal contribution to the expedition, especially her astute observations regarding the changes in riverside plant life, the diminishing stretches of sandy shores, and the proliferation of invasive species. Her life poignantly illustrated the river's condition prior to the dam's erection, highlighting the profound ecological consequences of human attempts to control nature. The insights from Jotter Cutter, along with contributions from other researchers and the memories of seasoned veterans, played a pivotal role in influencing the strategic choices made by the agency responsible for water management and development.

Clover and Jotter earned considerable acclaim for their pioneering work in scientific discovery and study following their journey of exploration in 1938.

Their successful river journey overturned the deep-seated prejudices that existed towards women engaging in adventurous, physically demanding scientific endeavors.

The narrative underscores the profound impact that Clover and Jotter's 1938 expedition had on the perception of women in scientific and exploratory roles. Despite societal norms that sought to confine women to less demanding roles, their skillful maneuvering through the challenging rapids of the Colorado River showcased their abilities and broke through conventional gender perceptions. Their steadfast commitment to exploring the unknown shone through as they bravely navigated dangerous waters, persevered in traversing wild landscapes, and triumphed over the skepticism of their male peers.

Clover and Jotter set a standard for future women in science and exploration through their successful expedition and notable botanical findings. Their courage and determination inspired more women to pursue their aspirations despite potential challenges. Their story powerfully challenges traditional views on the contributions of women and expands the range of recognized participants in scientific discovery.

Clover and Jotter's achievements, as well as the enduring legacy of their expedition, continue to inspire and educate future generations of explorers and scholars.

The concluding comments by Sevigny emphasize the enduring legacy of Clover and Jotter. The recognition of these scientists for their academic achievements in botany was almost eclipsed by journalists' emphasis on their audacious adventures, which tended to emphasize their being women. Their contributions have endured over time. Their names are still held in high esteem by botanists and river explorers, and as a tribute to Clover's enduring impact, a cactus is named after her (Sclerocactus cloverae), while in Utah, near the Colorado River, two side canyons are informally referred to in her honor and that of her colleagues. The botanical specimens they gathered remain accessible for study and analysis, offering scholars the chance to investigate environmental changes and build on their findings, housed within the collections of the Smithsonian and the University of Michigan.

Clover and Jotter's story demonstrates the profound impact that a mix of curiosity, dedication, and persistence can have on shaping scientific understanding and motivating subsequent generations. They broke through traditional barriers, creating a path for women in careers that were previously off-limits. Their passion for plant science and their eagerness to explore the treasures provided by the wild rivers embody the persistent essence of discovery and academic inquisitiveness.

Practical Tips

• You can start a personal project to document the biodiversity in your local area. Choose a specific location, like a nearby park or nature reserve, and make regular visits to observe and record the different plant and animal species you find. Use a journal or a digital app to note your observations, including the date, weather conditions, and any changes you notice over time. This practice will help you develop an understanding of your local ecosystem and its changes, much like Clover and Jotter's work did for the Grand Canyon.
• Create a visual timeline of environmental changes in a place you care about by collecting and comparing photographs from different years. Reach out to local libraries, historical societies, or use online resources to find historical images. Then, take current photos from the same vantage points. This will give you a visual representation of how the environment has changed over time, similar to how Jotter Cutter witnessed changes in the Colorado River.
• Engage with a citizen science project that focuses on environmental monitoring or species documentation. Many projects allow volunteers to contribute data through simple observations, which can be done with just a smartphone and an app. Your participation will contribute to larger scientific studies and help track environmental changes, echoing the impact of Clover and Jotter's expeditionary work.
