1970 Map of Glaciate Butte

About this map

Gifford Pinchot National Forest and the Yakima Indian Reservation meet in this 1970s record of a volatile volcanic landscape. Large fields of lava dominate the central and southwestern terrain, flowing from the heights of Potato Hill and surrounding peaks toward Foggy Flat. The map documents the boundary between managed timberlands and the Mount Adams Wilderness, where high-altitude water features like Two Lakes and the headwaters of Clearwater Creek are accessed by the Highline Trail and several Pack Trails. Local forest management is anchored at the Potato Hill Guard Station, situated near the Potato Hill Road. This survey provides essential detail for understanding the drainage patterns of the Muddy Fork and Cold Creek before modern reforestation changed the visibility of these ancient volcanic flows.
