Hidden Lake TOPO, Eagle Cap Wilderness—Alpine Lake at ± 2200 meters (7173 feet).

A high cirque located at the far Northwest end of the East Eagle Valley,
Hidden Lake is one the most beautiful jewels of the South Wallowas and
the Eagle Cap Wilderness. East facing, strikingly peaceful and feminine
in character, it is one of finest examples of an intact alpine watershed
I've ever seen.
