2020 Map of Greenhorn

About this map

Greenhorn and the nearby site of Robinsonville sit high in the Blue Mountains at the crossing of the Grant and Baker County lines. This 2020 map documents the complex terrain of the Elkhorn Range, where high-altitude water management is evident in features like the Placer Ditch and numerous gulches such as California Gulch and McWillis Gulch. The landscape is dominated by the intersection of three major forest boundaries: the Umatilla National Forest, Whitman National Forest, and Malheur National Forest. In the southern reaches, the geography softens into Whitney Valley and Taylor Flat, drained by the N Fork Burnt River. The presence of the Greenhorn Cem and the Austin Spur road provides tangible evidence of the area's gold-mining heritage and early transportation networks that once connected these remote mountain outposts.
