Episode Details

Mike DeHoff is the Principal Investigator at Returning Rapids Project, a one-of-a-kind project that is documenting the recovery of the Colorado River in Cataract Canyon, upper Glen Canyon, and along the San Juan. Back in 1963, the construction of Glen Canyon Dam created Lake Powell, which submerged many of the area's canyons– turning what were once wild stretches of the Colorado into flat water. Today, the southwest's ongoing historic drought has caused Lake Powell's water levels to drop significantly, revealing historic rapids, recently hidden geologic features, and riparian ecosystems that had been deep underwater for nearly fifty years.

Returning Rapids began as a personal project for Mike and three of his river-loving friends– Meg Flynn, Peter Lefebvre, and Chris Benson. They began to notice changes in the river created by Lake Powell's receding waters and started documenting those changes and using historic photographs and documents to better understand the reemerging landscape. Over the years, their work caught the attention of universities, academics, scientists, and government agencies, all of whom were fascinated by what was being discovered deep in those canyons. Fast forward to today, and their work is not only enabling cutting-edge research, but it's capturing the attention of bigtime media outlets, including a recent feature in Rolling Stone.

Mike connected with me virtually from his home base in Moab, Utah, and we had a fascinating discussion about the Colorado River, Lake Powell, and the history of the Returning Rapids project. We started out with a brief history lesson on the drought's effect on the Colorado River, then we dug into issues such as the mind-blowing amount of sediment created by Glen Canyon Dam. We discussed when Mike and his partners realized that their personal project was capturing the attention of the public, the challenges of garnering attention for lesser-known places like Cataract Canyon, and the idea of combining Lake Powell and Lake Mead. We also talk a lot about Mike's personal journey with this project, and how his willingness to follow his curiosity, partner with very smart people, take risks, and work extremely hard has had a significant scientific impact. We also discuss books, his mentors, his desire to learn from everyone he meets, and much more.

A huge thanks to Mike, Meg, Peter, and Chris for their important work, and for providing such a solid example for all of us who feel drawn to make a difference here in the American West.
