High Mountain Lake Research Natural Areas in Idaho
102 103 Little Granite Creek Lakes (W ellner 1979). The natural area spans elevations from abou 427 m (1400 feet)where Little Granite Creek flows into the Little Granite Creek Research Natural Area Snake River to 2863 m (9393 ft) at the summit of one of the Nezperce National Forest peaks. The proposed RNA will contain the entire drainage o Little Granite Creek except for some recreational exclusions. There are five lakes and five ponds in the proposed RNA. Norm Howse surveyed Echo Lake, Quad Lake, and He Devil Lake on August 7-11, 1967 (Howse 1967). Fred Rabe and Nancy Savage subsequently made observations of Baldy Lake and Ponds 1-3 on September 27-29, 1974. Triangle Lake was not sampled. Location The high lakes in the proposed RNAare located in two basins forming the headwaters of Little Granite Creek in the Hells Canyon National Recreation Area.

By trail, Quad Lake, He Devil Lake and Echo Lake are about 9 miles from the guard Station.
