Details
Lost Brother Butte is a dormant stratovolcano located in a west central Barlow County. Standing at 7,989 ft (2,435 m), it is the tallest point in the county. Though its origins are in debate, evidence suggest Lost Brother is part of the Cascade Volcanic Arc. Its latest active phase was 7,000 years ago. At present, there is minimal tectonic or magmatic activity within the mountain, though several fumaroles on the northeast side continue to vent steam and gas. The most recent eruption was andesitic, but the eruptive events which formed the volcano between 600,000-580,000 years ago were basaltic.
An effusive eruption dated at 500,000 years ago formed a long, eastward-trending ridge system. The Palmer River has subsequently eroded a valley through the ridge, dividing it into north and south spurs of the mountain. The town of Samuelton lies at the easternmost extent of the Palmer River Valley. The small villages of Crestview and Munro flank the western head of the valley.
Brother Drop Ski Resort can found on the southeast flank at an elevation of 4,416 ft (1,346 m).
