Mirror Lake State Park Campground Professional Guide
Detailed Trail Description from our Guidebook
"As you look out at the sandstone cliﬀs above the lake, you are looking back in time 500 million years to the Cambrian period, when this was all under the sea. The gorge that Mirror Lake occupies was formed quite suddenly in geological terms, when a glacial lake burst forth from its ice dam at the end of the most recent ice age and rushed through the soft rock.
A dam on Dell Creek created this lake, and the protective sandstone cliﬀs keep the waters still and give them that reﬂective character from which the lake takes its name. The picturesque lake, nearly 2,000 acres of forest, and 20 miles of hiking trails make up this park, which is a welcome contrast to the tourist trade at nearby Wisconsin Dells."
