Dalles << dalz >> are deep gorges where rivers flow rapidly over, or have cut through, hard rock or slabs. The name comes from a French word meaning slab or tile. The singular form of dalles in English is dell, and in many parts of the country these gorges are called dells instead of dalles. French explorers gave the name dalles to scenic gorges of North American rivers, especially those in the northern part of the United States. Notable dalles in the United States include the Wisconsin Dells on the Wisconsin River, near Wisconsin Dells, Wis.; the Saint Louis River Dalles near Duluth, Minn.; the Saint Croix River Dalles between Wisconsin and Minnesota; and The Dalles on the Columbia River between Oregon and Washington.
