1990 Map of Lord Flat

About this map

The Snake River carves a deep canyon boundary between Oregon and Idaho on this 1990 survey, defining a wilderness where high-elevation flats drop sharply into river-carved drainages. Human presence is sparse and functional, centered around isolated outposts like the Tryon Creek Ranch and Somers Ranch, while the Dorrance Cow Camp sits near the head of Buckaroo Gulch. The landscape is dominated by the Hells Canyon Wilderness, where the lack of developed roads is underscored by the presence of a primitive Landing Strip on the high ground near Lord Creek. Navigating the river corridor requires knowledge of successive whitewater features, including Highrange Rapids, Cottonwood Rapids, and Lookout Creek Rapids. The convergence of the Wallowa National Forest and Nez Perce National Forest highlights the managed but primitive state of this borderland at the close of the 20th century.
