North of Lander, WY, turn into the Shoshone National Forest and follow service roads up to Dickinson Park. Trail climbs a shoulder to the east before dropping down to the Popo Agie following the river first south then curving west toward the Cirque of the Towers. Only one river crossing is required as long as the bridge is not taken that lies about 1 mile downriver of the turnoff to the Cirque of the Moon. Wander instead through dense forest on the south side of the river until boulders appear from the talus bench leading into the cirque (open sky will also be visible). Floor of the cirque is largely boulders and rubble (a moonscape, if you will) but for one patch of tundra which has supported up to 3 tents and lies within a hundred yards of a tarn where water can be had.
