1988 Map of Broken Top

About this map

Broken Top and the surrounding high-altitude terrain of the Deschutes National Forest dominate this late-twentieth-century topographical survey. The landscape is defined by the remnants of volcanic activity and glacial movement, featuring the Bend Glacier and Crook Glacier carved into the mountain's northeast face. The map reveals a complex hydrologic system where high-country basins such as Green Lakes and Todd Lake feed various branches of North Fork Tumalo Creek and South Fork Squaw Creek. In the southern reaches, the Mt. Bachelor Ski Area and Egan Lodge indicate the area's development for recreation near Dutchman Flat. This provisional map provides a detailed view of the Three Sisters Wilderness boundary, showing the relationship between protected primitive lands and the seasonal infrastructures that support tourism in this part of the Cascades.
