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.
