About this map

Bonita stands as a primary point of reference in this high-desert landscape of eastern Oregon during the late twentieth century. The terrain is defined by the broad expanse of Cow Valley, a geographic basin framed by prominent volcanic features such as Worsham Butte, Saddle Butte, and Cow Valley Butte. A complex network of intermittent watercourses, including Cow Creek, Lyman Creek, and Blue Creek, drains toward the valley floor, illustrating the hydraulic patterns of this arid Malheur County environment.

Remote valleys and flats like Lost Valley and Rye Flat characterize the western reaches of the survey, while the northern boundary is marked by the rugged drainage of Hugg Creek and Grouse Creek. This document captures the intersection of traditional rangeland and the intricate topography of the Oregon high country, providing a clear record of the area's physical features before further modern developments altered the landscape.
