Lake Abert And Abert Rim


Basin and range converge at Abert Rim and Lake Abert, creating a unique rocky upland and a large lake and shoreline that attract contrasting wildlife. Abert Rim is the longest exposed fault scarp in North America, and one of the highest fault scarps in the United States. It towers over Lake Abert – Oregon’s only saltwater lake that attracts a diverse population of migratory waterfowl. After basaltic flood lavas covered much of eastern Oregon about 5 to 23 million years ago, great blocks of the Earths crust subsequently tilted, resulting in the raised scarp and lakebed seen today.
