Hello, we had some people drop out of this trip recently so we are on the lookout for some volunteers.I am on the lookout for some volunteers to help with our summer field sampling in the lower Little Colorado River, a tributary to the Grand Canyon. The volunteer would participate in one twelve day sampling trip to sample juvenile humpback chub (an endangered fish native to the Colorado River basin). The field work is very physically demanding as we spend 10+ hours per day hiking over rugged terrain in hot conditions (temperatures can be as high as 120 F, though the river is a pleasant temperature). Also, we work in remote conditions and have very limited communication with the outside world. Volunteers must be 18 years or older and need to be aware of the physical demands and remote conditions before committing. We access the canyon via helicopter, and volunteers would be required to take a 3-5 hour online training prior to the trip. Volunteers would be responsible for traveling to Flagstaff, Arizona, after which food costs and "accomodations" (i.e., camping) are covered.Trip dates: June 27-July 8 2019If interested, please contact:Maria Dzul, Fish BiologistU.S. Geological SurveyGrand Canyon Monitoring and Research Centermdzul@usgs.gov
I went on this trip last year, and will be heading out on this one as well. It's a great trip, but the conditions are quite harsh...
For reference, here's a GIF of coming in to land at one of the camps:
