Mount Pluto, California

Mount Pluto is a mountain summit in the Sierra Nevada region of Placer County, California, reaching 2,626 meters in elevation. The upper sections feature steep slopes with loose stones scattered across the hiking paths.

The peak formed approximately 2 million years ago through volcanic activity in the region. Lava flows and mudslides from that period shaped the surrounding landscape that visitors see today.

The Northstar California ski resort incorporates sections of Mount Pluto, establishing it as a central location for winter sports in the Sierra Nevada range point.

A chairlift system provides access to higher elevations and reduces hiking time. The best season for visiting is late summer through early fall when trail conditions are most favorable.

This peak ranks as the second highest among 156 elevated points throughout the county. A service road crosses its slopes and includes sections with steep grades that challenge even experienced drivers.
