About this map

Crater Lake National Park and Winema National Forest converge in this high-altitude landscape dominated by volcanic geology and timberlands. The northeastern boundary of the park is defined by the sharp descent into the Sand Creek drainage, where the Sand Creek Pinnacles and the nearby Pinnacles Trailhead mark significant geological landmarks of the Mazama eruption. The terrain rises to prominent volcanic heights including Boundary Butte, Dry Butte, and the long incline of Sun Mountain, reflecting the area's complex topographic character.

Industrial activity is evident through a scattered Quarry and Cinder Pit, while the presence of Egan Springs provides a rare water source in this porous volcanic soil. The map details the transition between protected park land and managed forest, including the Sun Pass area and the elevated Sand Ridge, illustrating the intersection of conservation and resource management in the Cascades during the late 1990s.
