About this map

Aneroid Mtn and the surrounding high country of the Eagle Cap Wilderness dominate this 1990 provisional survey, capturing a landscape defined by glaciated basins and alpine lakes. The geography is shaped by the headwaters of major drainage systems, including the West Fork Wallowa River and the three forks of the Imnaha River. Evidence of early twentieth-century resource exploration is found in several marked prospects and a tunnel near Aneroid Lake.

The map reveals a high-elevation environment where access is limited to a network of trails, such as the pack trail winding through McCully Basin. Significant landmarks like Cusick Mountain, Bonneville Mtn, and Petes Point provide vertical orientation across the Wallowa National Forest. This document preserves the late-century state of this protected area before more recent environmental shifts changed the character of its high-altitude meadows like Six Mile Meadow.
