About this map

Lassen Peak dominates the high alpine landscape of this 2012 survey, where thermal activity and volcanic geology define the terrain. The area is marked by geothermal features like Bumpass Hell, Sulphur Works, and Bumpass Hot Springs, alongside the dramatic heights of Brokeoff Mountain and Vulcans Castle. This section of the southern Cascades reveals a complex drainage network where Mill Creek and West Sulphur Creek carve through glacial meadows and canyons.

Lower elevations toward the southern boundary show signs of human infrastructure and recreation, including the Viola-Mineral Road and campgrounds such as Cowslip Campground and Bluff Falls Campground. Local landmarks like the Circle S Ranch and the presence of thermal waters at Growler Hot Spring and Morgan Hot Spring indicate the unique hydrothermal character that has long drawn visitors and settlers to these mountains. From the waters of Lake Helen to the depths of Blue Lake Canyon, the map provides a precise look at the wilderness and resource patterns of the early 21st century.
