A white-crowned sparrow (Zonotrichia leucophrys) sings from a distant tree branch, while a small stream burbles. Allsop Lake is the headwaters of the Left Hand Fork East Fork Bear River. The river emerges from the north end of the teardrop-shaped lake and flows down out of the High Uintas Wilderness, joining the Stillwater and Hayden Forks, eventually emptying into the Great Salt Lake.
