, with a vertical face
more than a quarter mile high, this 30-mile long
fault rises 2,000 feet above Lake Abert & 2,500
feet above the valley floor in the Great Basin
country of Eastern Oregon's high desert. It is
one of the largest, longest exposed fault
escarpments in North America. with an 800 foot
lava cap that ends in a sheer precipice. The
scarp is practically a perfect fault, and one of
the highest fault scarps in the world.
The rim began forming during geological upheaval
several million years ago. In in 1843 the Lake &
Rim were discovered by Lt. John Fremont and his

Stretching from the south end of Lake Abert to
Alkali Lake, this is the best area to view
bighorn sheep. One of the most popular spots is
above the geologic point of interest sign near
mile marker 81. Bighorn sheep were transplanted
to the rim in 1975 and 1977 from nearby Hart
Mountain. At the shoreline numerous western
snowy plover, one of the largest breeding
populations of such species in the world, are
easily seen swimming in small three inch
circles, stirring up the brine shrimp, for a
steady diet in this salty habitat. Also watch
for raptors, such as ferruginous hawk, soaring
above the lake.

Rim Photo above was taking around 1960.
