Elliott Corbett Memorial State Recreation Site, State recreation site on Blue Lake in Jefferson County, Oregon, United States

Elliott Corbett Memorial State Recreation Site covers 63 acres of ponderosa and lodgepole pine forest and a large open meadow above the south shore of Blue Lake, a volcanic maar 314 feet deep. Elevation runs from 3,468 feet at the lakeshore to over 3,600 feet on the slopes. Two seasonal drainages cross the land, and the steep crater walls make the shoreline hard to walk.

The central meadow served as a vital rest stop for 19th-century pioneers crossing the Cascade Range, offering water and grazing land. This location remained important as a waypoint for travelers moving through this rugged mountain region.

The park carries the name of Elliott R. Corbett II, an infantryman killed in action on 19 November 1944, aged 22, and buried at the United States Military Cemetery at Margraten in the Netherlands. His parents, Henry L. and Gretchen Corbett, gave the land to the people of Oregon in 1952 on the condition that it stay a wilderness area.

There is no road into the park; from the west, the trail starts at a small parking area on Forest Service Road 2076, three-quarters of a mile south of Highway 20, and runs 2 miles east to the main meadow. From Camp Caldera in the east, the Blue Lake Crater Rim Trail reaches the park, but the trail along the east side of the lake crosses private property. The full loop around the lake is about 2.5 miles. Potable water, toilets and signage are not provided, and snowmobiles are banned year-round.

Blue Lake fills a volcanic maar to a depth of 314 feet, one of the deepest lakes in Oregon. Its only outlet is Link Creek, which starts at the north end opposite the park and reaches Suttle Lake 0.6 miles downstream. Osprey and bald eagles stay into the fall to feed on brown trout and kokanee salmon spawning in the creek.
