Gifford Pinchot National Forest encompasses the entirety of this landscape, dominated by the peaks and drainages of the Cascade Range. The eastern portion of the map is defined by the Trapper Creek Wilderness, where high points like Observation Peak and Soda Peaks overlook the headwaters of Trapper Creek. To the west, the terrain is carved by the Siouxon Creek system, including Horseshoe Creek and Calamity Creek. The network of trails, such as the Siouxon Trl and Observation Peak Trl, reveals a landscape managed for recreation and conservation. Geological features like Sister Rocks and Bare Mtn stand as landmarks among the dense timber, while Soda Peaks Lake provides a high-elevation water feature. This survey captures the topographical complexity of the region before any modern alterations to these protected wilderness boundaries.
