1992 Map of Big Mowich Mountain

About this map

Big Mowich Mtn and Little Mowich Mtn dominate the high country at the intersection of the Ochoco National Forest and Malheur National Forest. This interior Oregon landscape, surveyed in the early 1990s, reveals a network of high-elevation meadows and springs that supported seasonal ranching operations like Harris Ranch, J M Ranch, and Allison Ranch. The terrain is deeply carved by drainage systems including Howard Valley and the headwaters of the South Fork Beaver Creek, with numerous water sources such as Stinking Spring and Button Flat Spring essential for livestock and forest management. The presence of a Sewage Disposal Pond and several Quarry sites suggests localized infrastructure supporting the forest service and ranching activities that define this part of the Grant and Harney County border.
