About this map

Mount Thielsen dominates this section of the High Cascades, anchoring a landscape defined by sharp ridges and a network of high-altitude drainages. In 2011, this area within the Oregon Cascades Recreation Area shows a transition from the volcanic peaks to the more sheltered drainage basins below. The terrain is marked by prominent geological features such as Sawtooth Ridge, Hollys Ridge, and Howlock Mountain, which separate the various creek systems including Tipsoo Creek and Thielsen Creek.

While the map primarily displays physical geography, the presence of Thielsen Camp and the curious label of Wits End suggest the long-standing human presence in these woods, likely tied to seasonal camping and backcountry exploration. The hydrography is particularly detailed, tracing the headwaters of numerous streams like Porcupine Creek, Spruce Creek, and Tiny Creek as they descend from the snowfields and ridges of the Cascades.
