Summit:
W7I/IC-187
Indian Post Office is an intriguing name given to a rounded high point qualifying as a SOTA summit along the Nee Me Poo, a trail of the Nez Perce and the Lewis and Clark trail. I searched the few vertical rock outcrops looking for what I thought might be pictographs or petroglyphs. I found neither. I did see a large rock cairn linked to folklore.
