About this map

The Strawberry Range and Aldrich Mountains dominate this high-elevation landscape within the Malheur National Forest. This 1990 provisional edition, based on photography from the mid-1980s, documents a remote wilderness defined by steep drainages like Big Canyon and Quiner Canyon. The map reveals a specialized resource geography, where the rugged peaks of Table Mountain give way to named watering points essential for forest management and local wildlife, including Chamber Spring, Steagall Spring, and Crazy Spring.

Evidence of human activity is sparse but specific, marked by a single Quarry and the open expanses of Powell Meadow and Wendling Glade. The drainage patterns are clearly defined, with the West Fork and Bear Valley Creek cutting through the southern reaches of the quadrangle. For the researcher, this sheet preserves the exact placement of interior forest trails and remote springs before later decades of environmental change and administrative updates altered the documented forest infrastructure.
