Dome Cascade is a 90-foot waterfall on Roaring Fork in Sevier County, Tennessee, in the Blue Ridge region. It lies about 5.4 miles southeast of Gatlinburg and roughly 33.9 miles southeast of Knoxville as the crow flies.
At 90 feet it stands in the tallest quarter of Tennessee’s 332 waterfalls with a recorded height, ranking 27th; the typical Tennessee waterfall is about 30 feet. By form it is a horsetail, where the water keeps some contact with the bedrock as it falls.
The Blue Ridge is the highest part of the southern Appalachians, a range of forested peaks and coves with oak, hickory, tulip poplar and hemlock and spruce-fir on the summits, in one of the wettest climates in the East. Steep mountain streams drop over granite, gneiss and quartzite ledges, giving the region hundreds of waterfalls. Roaring Fork carries 5 recorded waterfalls; the biggest of them reaches 140 feet.
Sevier County holds 37 recorded waterfalls, and several are close by. Twin Falls, a 140-foot horsetail waterfall, is under a mile away. Upper Grotto Falls, 20 feet high, is under a mile away. Grotto Falls, a 25-foot plunge waterfall, is about 1 miles away.
