Question 1

What is Fatwoman Lake (Crater Lake) and what activities are available?

Accepted Answer

Fatwoman Lake, located in the remote reaches of Johnson County, Wyoming, stands as one of the most intriguing and mysterious bodies of water in the Bighorn Mountains. Despite its lack of a fish population, the lake captivates visitors with its dramatic natural features, exceptional depth, and secluded alpine setting. Surrounded by steep granite walls, towering pine forests, and rocky outcrops shaped by millennia of glacial activity, Fatwoman Lake is a striking example of untouched wilderness in the Bighorn National Forest. Its clear, dark-blue waters and isolated location make it a favorite destination for adventurous hikers, backpackers, and wilderness photographers seeking quiet solitude far from developed trails. 

With an impressive maximum depth of 166 feet and an average depth of 78 feet, Fatwoman Lake is among the deepest natural lakes in the region. These extreme depths suggest a glacial origin, likely formed during the last Ice Age when massive glaciers carved out deep basins in the high mountain terrain. Today, the lake&rsquo;s cold, oxygen-poor depths make it unsuitable for sustaining fish populations, which explains the absence of any frequently caught or resident species. However, this lack of aquatic life enhances the lake's scientific interest, drawing attention from geologists and limnologists studying glacial basins and high-altitude water bodies. 

Though it doesn&rsquo;t support fishing, Fatwoman Lake offers a unique and rewarding experience for visitors interested in high-elevation ecosystems, geology, and raw natural beauty. The surrounding environment is rich in biodiversity, including hardy alpine vegetation, wildflowers, and wildlife such as marmots, pikas, mule deer, and the occasional mountain goat. Birdwatchers might also spot raptors and high-mountain songbirds navigating the thermals and forest edges. The lake&rsquo;s inaccessibility ensures minimal human impact, preserving its pristine condition and offering an unspoiled escape into nature for those willing to make the journey. 

Fatwoman Lake exemplifies the rugged allure of Wyoming&rsquo;s high country&mdash;untouched, dramatic, and deeply connected to the geological history of the Bighorn Mountains. While it may not appeal to anglers, it provides a rare opportunity to experience the raw, elemental power of the mountains. Its sheer depth, isolation, and glacial past make it not just a scenic destination but a natural wonder that showcases the forces that shaped the wild landscapes of northern Wyoming.
