Water is the carver of the Grand Canyon and the lifeblood of its many biotic communities. Though much is known about the storied Colorado River, relatively little is understood about the numerous cascades, trickles and occasional torrents that emerge from the canyon’s ancient rock strata. These more humble water sources sustain most of the living organisms in Grand Canyon. Spring-fed streams in particular play a vital role in a region where rainfall is scarce. This “hands-on” class will study and inventory a number of these oases, and assist in the gathering of hydrologic and biologic data to further the park’s understanding of these vital resources. After a thorough orientation on the South Rim, the class will embark on this moderate-intensity backpack down the stunning Hermit Trail to a camp for several nights beside tranquil Hermit Creek. After several nights exploring this area, including a day hike to thundering Hermit Rapid on the Colorado River, the group will follow the Tonto Trail several miles to Boucher Creek. After a few additional days in Boucher Canyon, the group will ascend the historic Boucher Trail back to the South Rim. Study sites will include such gems as Santa Maria Springs, the Hermit Creek narrows, Travertine Canyon, Boucher Creek and Dripping Springs.

Note: no previous surveying experience is required.
