Activity Notes

Permits are secured for 8/17/2024 to replace the Diamond Peak climb which is now closed due to fires. This is a one-day, car-to-car climb. We will meet at the Devils Lake/South Sister/Moraine Lake Trailhead where, on August 17th, we will depart the parking area at 6:00 AM. The round-trip climb distance is about 10 miles. The overall elevation gain is approximately 5,000 feet. There will be some scree scrambling, but this is not a technical climb. Nonetheless, we will move swiftly to return by 4:00 PM. So climbers must be in excellent condition and know their limits. Those who cannot keep up may be turned back.
