Avon serves as the primary settlement hub in this part of the Avon Valley, where the confluence of several mountain drainages meets the valley floor. The map highlights a landscape defined by its high-altitude topography, featuring Black Mtn and the prominent Illinois Ridge. Significant for recreation and modern conservation, the Continental Divide National Scenic Trail winds through the eastern heights within the Helena National Forest, tracing the boundary between Powell and Lewis and Clark counties.
