About this map

The Deschutes River carves a deep, serpentine path through this 1962 survey of the high desert border between Wasco and Sherman counties. The industrial heart of this remote corridor is defined by competing rail lines, specifically the Spokane Portland and Seattle River and the Oregon Trunk, which follow the narrow river canyon floor. Small railroad-oriented settlements like Sinamox and Oakbrook appear as vital outposts in a landscape dominated by dramatic vertical relief.

The surrounding plateau is etched by numerous drainages, including Jones Canyon, Rattlesnake Canyon, and French Canyon, which feed toward the central river valley. Significant landmarks such as Tygh Ridge rise above the canyon walls, while local resources are highlighted by a Quarry and various water sources like Elder Creek and numerous springs. This map provides a clear look at the infrastructure required to navigate and inhabit the rugged interior of north-central Oregon in the mid-20th century.
