About this map

Lost River Range peaks dominate this section of the Challis National Forest in Butte County. The landscape is defined by a series of deep drainages, including Cedarville Canyon and Brier Canyon, that cut through the high terrain. The eastern edge of the map descends toward the Little Lost River Valley, where the steep topography of the mountains meets the more open valley floor.

Modern recreational and access routes are well-documented, tracing the same natural corridors used for generations. The Taylor Canyon-Arco Pass Trl and Hurst Canyon Trl provide passage through the interior, while Pass Rd connects the namesake Arco Pass to the surrounding region. The presence of Hurst Creek and numerous named canyons like Horsethief Canyon and Briggs Canyon indicates a complex system of seasonal water flow and traditional travel ways through this segment of the Idaho backcountry.
