About this map

Greenhorn and the nearby site of Robinsonville anchor this survey of the high mountain terrain along the border of Baker Co and Grant Co. This area, deeply marked by its mining heritage, features numerous drainages like Quartz Gulch, Three Cent Gulch, and California Gulch that hint at the gold-seeking history of the region. The map provides a detailed look at the hydraulic infrastructure of a bygone era, specifically the Placer Ditch which cuts across the slopes above Greenhorn Cr.

Transitioning from the steep ridges of Olive Butte and the Umatilla National Forest, the landscape opens into broader clearings such as San Lou Flat and Whitney Valley. The drainage systems are intricate, with the N Fork Burnt River and S Fork Beaver Cr drawing from the surrounding heights of the Whitman National Forest. Local genealogists can locate the Greenhorn Cemetery, while land researchers can trace the forest development roads that wind toward Howard Meadow and Lobelia Meadow.
