Summary

[edit]
Description Abert Rim in Lake County, Oregon is one of the highest fault scarps in the United States. It rises 2500 ft above the valley floor, finishing with an 800 ft sheer-sided basalt cap. It was formed during the Miocene epoch. At that time basaltic flood lavas covered much of eastern Oregon. In subsequent faulting, great blocks were tilted and Abert Rim is at the western end of one of these blocks, while Lake Abert lies on top of another. Stretching more than 30 miles from Lakeview north to Alkali Lake, Abert Rim is also the longest exposed fault scarp in North America. Bighorn sheep were transplanted to the rim in 1975 and 1977 from nearby Hart Mountain, and are often spotted from the Abert Rim geologic point of interest sign located along Highway 395. Raptors, such as the Ferruginous Hawk, are also common in the area. The Chewaucan River enters the lake from the south, however it has no outlet. The lake level varies depending on rainfall and it nearly completely dried up 140 years ago. It is one of the Great Basin lakes. The escarpment and lake were first mapped on December 20, 1843 by John C. Frémont who named it after Colonel John James Abert, his commanding officer.
