About this map

Lone Mountain dominates this high-desert landscape in Harney County, serving as a prominent landmark in an area defined by its scarce but vital water sources. The 1981 data records a network of isolated springs and livestock management features, such as Winnemucca Spring, Black Rock Spring, and Buck Spring. The presence of a Corral and several locations marked Guzzler—artificial water collectors for wildlife or range stock—indicates the area's primary use for grazing and conservation during the late twentieth century.

Steep terrain transitions from the high peaks of the mountain down into Long Draw, eventually leveling out onto the broad expanse of Big Spring Table. This survey, based on 1974 aerial photography, provides a clear view of the complex topography of Buck Buttes and the winding course of Long Hollow Spring, illustrating how water and geography dictated the movement of people and livestock in this corner of Oregon.
