Details
Lost Brother Butte is a dormant stratovolcano located in west central Barlow County. Though geologically unrelated to the Three Sisters, the mountain's name reflects the belief of early white settlers that the peak was a distant part of the Three Sisters chain. At present, geological evidence suggests Lost Brother has more in common with the Newberry Volcano south of Bend, Oregon.
Standing at 7,929 ft (2,417 m), Lost Brother Butte is the tallest point in the county. Though its origins are in debate, evidence indicates the mountain 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 vent steam and gas at intervals. The existence of these fumaroles and several area hot springs at indicate the volcano has the potential to become active again.
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 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 4,336 ft (1,322 m).
