Had to hike this one from the Targhee Creek Trailhead since the Mile Creek trail was closed by the forest service due to a carcass in the area and they didn't want "humans" in the area. The threatened 5000 dollar fine/6 months in jail was sufficient to get my friend Dennis Poulin and I to try the Targhee Creek route.
Over 18 miles and we carried pepper spray. mrh has done an excellent job with this page and we felt it was the central ridge area that had the highest spot. The southern area had a nice cairn and I found a small film cannister register but unfortunately, the paper inside was soaked and not legible. We took a short cut down to Clark Lake and that way would make a better way to ascend to the highpoint area as well if you didn't intend to climb Targhee Peak. No grizzlies sighted on this trip (whew)
