Red Slate Mountain

The most common route to Red Slate Mountain's summit is a Class 2 scrambling path accessible from McGee Pass. This approach typically begins from the McGee Creek Trailhead, often involving an overnight stay at Big McGee Lake to break up the ascent. For experienced mountaineers, the North Couloir offers a long, technical snow climb, and both the North and South sides provide options for ski mountaineering.

Red Slate Mountain is considered a challenging hike. While the Class 2 scrambling route from McGee Pass is not overly technical, it requires good fitness and a head for heights due to the high elevation and rugged terrain. The mountain reaches an elevation of approximately 13,123 to 13,129 feet (4,002 meters), meaning significant elevation gain is involved from the trailhead.

Yes, permits are generally required for overnight stays in the Sierra Nevada wilderness, including areas around Red Slate Mountain. Day-use permits might also be necessary depending on the specific trailhead and season. It's crucial to check with the local ranger station (e.g., Inyo National Forest) for the most current permit requirements and to secure them in advance, especially for popular entry points like McGee Creek Trailhead.

While many trails in the Sierra Nevada allow dogs, specific regulations can vary by wilderness area and national forest. It's advisable to confirm with the Inyo National Forest or relevant land management agency regarding current rules for dogs on trails leading to Red Slate Mountain, especially concerning leash laws and waste removal. Always ensure your dog is prepared for rugged, high-altitude terrain.

The best time for hiking and scrambling Red Slate Mountain is typically during the summer months, from late June through September, when snow has largely receded from the Class 2 routes. Early season (June) may still involve significant snow patches, while late season (October) can bring colder temperatures and early snowfall. Always check weather and trail conditions before planning your trip.

Winter ascents or ski mountaineering on Red Slate Mountain require specialized gear due to challenging conditions. Essential items include ice axe, crampons, helmet, avalanche safety equipment (beacon, shovel, probe), appropriate layering for extreme cold, waterproof outer shells, and navigation tools. Experience in winter mountaineering and avalanche assessment is crucial.

While the summit of Red Slate Mountain itself is a challenging endeavor not suitable for young children, the lower sections of the McGee Creek Trail, which serves as an approach, offer more moderate, family-friendly hiking opportunities. Trails leading to Little McGee Lake or Big McGee Lake provide beautiful scenery with less strenuous elevation gain, perfect for families looking for a day hike in the area.

Access to Red Slate Mountain typically begins from the McGee Creek Trailhead, which has a designated parking area. Parking can fill up quickly, especially during peak season and on weekends, so arriving early is highly recommended. Public transport options directly to the trailhead are limited; most visitors rely on personal vehicles. Carpooling is encouraged to reduce congestion.

Red Slate Mountain is named for its distinctive red granite summit, composed of metamorphic rock, primarily slate, dating back to the Paleozoic Era. The region north of the mountain is also notable for its seismic activity, linked to the Long Valley Caldera, a large volcanic area. From the summit, hikers can observe various prominent peaks and the vastness of the Sierra Nevada landscape.

Red Slate Mountain is located in a wilderness area, so there are no immediate cafes or restaurants at the trailhead. However, the nearby town of Mammoth Lakes, a popular resort community, offers a wide range of dining options, grocery stores, and various types of accommodation, from hotels and motels to vacation rentals and campgrounds. It serves as an excellent base for trips to the region.

The Sierra Nevada is home to diverse wildlife. Hikers on trails around Red Slate Mountain might encounter various species, including marmots, pikas, deer, and a variety of birdlife. While less common, black bears are present in the region, so it's essential to practice bear-safe food storage and carry bear spray. Always observe wildlife from a respectful distance and never feed animals.
