About this map

Opal Mountain dominates the central landscape of this 1990s survey, marking a high point in the high-desert timberlands where the Jefferson Co Crook Co line bisects the Och Oco National Forest. The map documents a rugged interior geography defined by the protected Mill Creek Wilderness to the south and the dramatic basaltic formations of the Och Oco Mountains.

Evidence of seasonal ranching and logging history is found at the Trout Creek Cow Camp and Symons Wood Camp, illustrating the specialized land use in this part of central Oregon. The terrain is deeply incised by drainages like Trout Creek and Opal Creek, punctuated by distinctive landmarks such as Skookum Rock and Rooster Rock. Numerous springs, including Keller Cabin Spring and Bingham Spring, provide the critical water sources that supported early cattle operations and the established Roundup Grounds.
