During our trip from Flaming Gorge Dam to Split Mountain we observed a variety of mammal species. Our observations were made either with visual sightings, tracks, or scat. Due to our limited survey time we were rarely unable to observe more than a few of any one species, often times only seeing one individual of a species. This list is not limited to the species that I personally saw but also includes those animals reported to me by my colleagues on this research trip.
The only presence of a black bear we discovered was this large track (left) at our Red Creek confluence survey site at river mile 278.8. This deer fawn (right) we chanced upon during our Red Creek confluence survey site (species unknown: either mule deer or white-tailed deer). Photos: Julia Halverson
Beaver tracks (right, and right of the shoe print in the picture) were found in our Lower Brown’s Park sandbar survey site at river mile 257.8. This muskrat skull (right) was still attached to a dead muskrat at the same survey site. Photos: Lacy Smith (left) and Julia Halverson (right)
These bighorn sheep (left) were seen near our Sage Creek survey site at river mile 217. This mule deer (right) was seen in Rainbow Park as we were floating down the river. Photos: Jeff Mount (left) and Lacy Smith (right)
