1970 Map of Morrell Lake

USGS Topo · Published 1973

About this map

The high alpine terrain of the Missoula and Powell County line is defined by dramatic peaks and glacier-carved basins in the early 1970s. This survey, compiled from 1969 aerial photography, documents the interface of the Bob Marshall Wilderness Boundary, the Lolo National Forest, and the Flathead National Forest. Significant water features like Morrell Lake, Florence Lake, and the cascade at Morrell Falls serve as focal points for the backcountry drainage systems of Morrell and Marshall Creek. The map provides a precise record of established routes through the mountains, such as the Pyramid Pass Trail and the high Pyramid Pass, essential for navigating the complex geography around Grizzly Basin. Prominent summits including Fisher Peak and Marshall Mountain anchor the high-altitude landscape of this protected wilderness area.
