About this map

Crater Lake National Park dominates the southern half of this landscape, where the volcanic profile of Timber Crater rises as a central landmark. The terrain transitions north into the Winema National Forest and the Mount Thielsen Wilderness, reflecting a high-altitude environment shaped by ancient eruptions. The presence of the Pumice Desert in the west illustrates the stark geological legacy of the region, where thick volcanic deposits have limited vegetation growth for millennia.

Long-distance travel through this wilderness is marked by the Pacific Crest National Scenic Trail, which winds past Grouse Hill and a designated viewpoint near the park boundary. Administrative and industrial history is noted by the Entrance Station and a solitary quarry near Summit Rock. The intersection of the Umpqua National Forest and Oregon Cascades Recreation Area highlights the complex management of these Cascades highlands at the close of the twentieth century.
