Email your answer: Where is the esker in relation to the lake?
Gobler Lake was designated a State Natural Area (SNA) in 1974. SNAs protect outstanding examples of Wisconsin's native landscape of natural communities, significant geological formations and archaeological sites. Encompassing nearly 400,000 acres, they are valuable for research and educational use, the preservation of genetic and biological diversity and for providing benchmarks for determining the impact of use on managed lands. (For rules governing state-owned SNAs and other state lands, please consult Chapter NR 45 Wis. Admin. Code.)
Gobler Lake SNA (1,085 acres) contains a geologically significant esker. Gobler Lake is 20-acres, with slightly acidic water of moderate transparency and a maximum depth of 8 feet. The esker is wooded with white pine. The wild character is reduced only by the road, which follows the esker.
What is an esker? A sinuous (many curves and turns) rounded ridge of sand and gravel deposited by streams that flowed through tunnels at the base of a glacier. Look around you. Can you see the esker here at the Gobler Lake State Natural Area? Recent glacially deposited soil, gravel and boulders can be found in areas of almost every Wisconsin county, deposited during the most recent period of the Ice Age which ended about 10,000 years ago, known as the Wisconsin Glaciation.
