is located in the Southern-central area of Oregon,
south-central Lake County, about 30 miles north of
Lakeview, on the west side of Highway 395.
One of the largest lakes in Oregon, with no outlet,
water can only leave by evaporation. As a result, sodium
carbonates and other salts become concentrated in the
lake's waters. Note image of white rock showing effects
of alkalinity. The shore line image above of white is a
field of such rocks. Abert Rim stretches 30 miles north
to south. Lake Abert normally covers 60 square miles
however the lake varies in size from year to year
depending upon precipitation. It went almost completely
dry 140 years ago. Elevation is 6,250 feet.
It is not uncommon to see mule deer
traversing the mountain and country side in this area.
Abert Rim - 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 party while searching for the mythical
Buena Ventura River that was thought to flow from
Klamath Lake into San Francisco Bay. Fremont named the
lake and rim after his commanding officer, Colonel J.J.

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.
