Gamma Hot Springs

## Overview Gamma Hot Springs is a remote, free-access natural hot spring located in the North Cascades region of Washington State, at an elevation nestled deep within the rugged wilderness near the crest of the Cascade Range. Situated at approximately 48.17°N, 121.08°W, the spring lies in a dramatic alpine landscape shaped by volcanic and geothermal activity — a hallmark of the Cascade volcanic arc, where tectonic forces drive heated water to the surface through fractured bedrock. The North Cascades are home to a handful of natural hot springs, many of which have been used by visitors and locals for generations. Gamma Hot Springs is one of the lesser-known geothermal features in the area, offering a more secluded and undeveloped soaking experience compared to some of the region's more popular hot spring destinations. Due to its remote location, it tends to attract experienced hikers and hot spring enthusiasts seeking a backcountry adventure. As with all wild hot springs, water temperatures can vary seasonally and between individual pools. Visitors have historically reported that the water is naturally heated and suitable for soaking, though conditions may change with weather, snowmelt, and seasonal water flow. ## Directions 1. Gamma Hot Springs is located in the North Cascades of Washington, east of Darrington and south of the Glacier Peak Wilderness area. 2. The GPS coordinates for the spring are **48.169736, -121.076157**. It is recommended to load these coordinates into a GPS device or offline mapping app before heading out, as cell service in this area is extremely limited. 3. Access likely requires a backcountry hike through rugged, mountainous terrain. Be prepared for trail conditions that may include river crossings, steep elevation changes, and unmarked paths. 4. Check current trail and road conditions with the Mount Baker-Snoqualmie National Forest ranger station or the Darrington Ranger District before your trip, especially in spring and early summer when snowpack may block access. *Note: Detailed trailhead directions and route descriptions for Gamma Hot Springs are not widely documented. If you have visited and can share specific route information, your contributions would be invaluable to fellow visitors.* ## What to Expect Gamma Hot Springs is an undeveloped, backcountry hot spring in a wild and remote setting. Expect a true wilderness experience — there are no facilities, signage, or maintained infrastructure at the site. - **Terrain:** The surrounding landscape is characteristic of the North Cascades: dense old-growth forest, alpine meadows, and rocky volcanic terrain. The area is known for its stunning scenery, wildlife, and solitude. - **Water:** As a natural geothermal feature, the hot spring water is heated underground and rises to the surface. Water temperature and flow can fluctuate depending on the season and recent precipitation. Some natural hot springs in this region have been reported to contain trace minerals from the volcanic geology. - **Access:** This is a backcountry destination. Visitors should be prepared for a multi-mile hike with appropriate gear, including navigation tools, layers for changing mountain weather, and sufficient food and water. A Northwest Forest Pass or similar recreation pass may be required for trailhead parking. - **Seasonal Notes:** The best window for visiting is typically mid-summer through early fall (July–September), when snow has melted and trails are more passable. Winter and spring access may be extremely difficult or dangerous due to avalanche risk and deep snowpack. - **Leave No Trace:** As an undeveloped natural feature, please practice Leave No Trace principles. Pack out all trash, avoid altering the natural pools, and respect the fragile alpine environment.
