Deep Lake

Deep Lake, nestled at the base of Gannett Peak – Wyoming's highest mountain – offers an unparalleled high-alpine fishing experience. This remote gem sits at over 10,500 feet and is surrounded by a rugged, glaciated landscape that feels truly wild. While the primary draw here for anglers is the prospect of strong, wild cutthroat trout, the sheer majesty of the scenery, dominated by towering granite walls and active glaciers, is a close second. The lake itself is appropriately named, plunging to significant depths that support a healthy fish population, often larger than those found in shallower alpine tarns. This isn't a casual hike; reaching Deep Lake is a serious multi-day expedition into the heart of the northern Winds, requiring commitment and solid backcountry skills. Access is most common from the Elkhart Park Trailhead, typically via Seneca Lake and the Indian Basin Trail, a journey that can take 2-3 days of strenuous hiking to reach. The final approach involves navigating challenging, often rocky and off-trail terrain. The ideal season is late July to early September, when snow has melted enough to permit passage and fishing conditions are stable. This is a trip for experienced backpackers comfortable with high mileage, significant elevation gain, and self-sufficiency in remote wilderness. No specific permits are required beyond standard wilderness regulations, but preparation for extreme conditions is a must. The solitude here is profound, a stark contrast to more accessible lakes. **Highlights** * Elevation: ~10,560 feet * Target Species: Yellowstone Cutthroat Trout * Location: Base of Gannett Peak, Wyoming's highest * Scenery: Glaciated peaks, dramatic cirques, true high-alpine environment * Remoteness: Requires multi-day, strenuous backpacking * Fishing: Healthy population of wild cutthroat **Watch-outs** * Remoteness: Very remote, far from trailheads, requires extensive planning * Navigation: Can involve off-trail travel and route finding in challenging terrain * Weather: Highly unpredictable and severe alpine weather, including snow in summer * Grizzly Bears: High probability of bear encounters; extreme caution and food storage essential
