The Cline Buttes are mountains with volcanic origins that form three dome-shaped peaks located in Deschutes County in central Oregon.

They are some of the easternmost foothills of the Cascade mountain range, located near the northwest corner of Oregon's high desert country.

The Cline Buttes have been significantly eroded over time, leaving a rounded dome shape with three separate crests.

They are now covered with 10 to 20 inches (25 to 51 cm) of sandy loam soil in most areas with rhyolite and basalt outcropping on the steeper slopes.

[5][6][7][8] The rhyolite lava flow deposits at Cline Buttes show a roughly porphyritic texture, with oligoclase phenocrysts making up between 1 and 2 percent of the minerals.

[7] Cline Buttes volcanoes also produced rhyodacite, which varies in color from light gray to red-brown and are similarly sparsely porphyritic.

Low groundcover plants includes Granite Gilia, rough eyelash, Longleaf hawksbeard, and bunch grass.

Larger mammals found in the area include black-tailed deer, elk, coyotes, black bear, bobcats, and cougars.

Birds of prey found in the area include golden eagles, red-tailed hawks, northern harriers, and prairie falcons.

[16][15] While prairie falcons are uncommon in most parts of central Oregon, the area around the Cline Buttes has a native breeding population.

At its peak, the town of Cline Falls had a post office, a school, two stores, two hotels, a newspaper, a power plant, and 500 residential lots for sale.

However, the community eventually failed when the first railroad route through the area was built on the opposite side of the river, through the neighboring town of Redmond.

[7] In the summer, recreation opportunities in the Cline Buttes area include hiking, horseback riding, mountain biking, bird watching, and scenic viewing.

[11][30] From the summit of the Cline Buttes, visitors have an excellent view of Cascade peaks to the west as well as the high desert country of Deschutes and Crook counties to the east.

To the northeast lies Smith Rock State Park, and farther to the east are the Powell Buttes and the Ochoco Mountains.
