Alaskan Thermokarst Lakes Contribute to Climate Change
- "Big Trail Lake is a thermokarst lake, which means it formed due to permafrost thaw. Permafrost is ground that stays frozen year round... When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born." - Excerpt from NASA
