. The community is in an arid, sparsely populated part of the state, along
Oregon Route 140, about east of
Lakeview. The
Warner Valley surrounding Adel contains many marshes and shallow lakes, most of them intermittent.
Frequented by
Native Americans for many thousands of years, the valley became a region of sheep grazing and cattle ranching by the late 19th century. Adel's infrastructure includes a combined store/restaurant/bar, a post office (serving
Zip Code 97620), an elementary school, and a church. Hot springs and related geological features have made one of the nearby ranches a potential site for a
geothermal power station.
History
People have lived in the Warner Valley for more than 10,000 years. Evidence of Native American occupation includes

Geography

Adel lies along Oregon Route 140 about east of Lakeview in south-central Oregon. From its intersection with the main highway, Plush–Adel Road runs north along the western shore of Crump and Hart lakes in the Warner Valley while Twentymile Road runs south from Adel to northern California just west of that state's border with Nevada. Deep Creek, flowing east from the
Warner Mountains, passes through Adel into marshlands and Pelican Lake before entering Crump Lake.
Adel is above sea level.
To the northeast, the Hart Mountain ridge rises to .
The region is moderately geologically active with a retired geyser and several hot springs. Geothermal exploration at the Crump Geyser site in 2010 found hot springs with temperatures as high as , two shallow wells with temperatures to , and a parent source of up to .
