1969 Map of Arco Pass

USGS Topo · Published 1992

About this map

Challis National Forest dominates this high-altitude landscape in the Lost River Range, where the terrain transitions sharply into the Little Lost River Valley. Surveyed in the late 1960s, the map reveals a network of canyons including Cedarville Canyon, Taylor Canyon, and Horsethief Canyon that carve through the mountain slopes. The namesake Arco Pass serves as a critical geographic notch in the range, connected by primitive 4WD tracks that follow natural contours. Vital water sources like Brier Springs and Hurst Creek are mapped in detail, showing the scarce but essential riparian points in this arid environment. The spatial arrangement of these springs and canyons highlights the historical routes used to navigate the rugged passage between the mountain peaks and the broad valley floor.
