Broken Top is a glacially eroded complex stratovolcano. It lies in the Cascade Volcanic Arc, part of the extensive Cascade Range in the U.S. state of Oregon. Located southeast of the Three Sisters peaks, the volcano, residing within the Three Sisters Wilderness, is 20 miles (32 km) west of Bend, Oregon in Deschutes County. Eruptive activity stopped roughly 100,000 years ago, and erosion by glaciers has since reduced the volcano's cone to where its contents are exposed. There are two named glaciers on the peak, Bend and Crook Glacier.
Camp Lake is a small alpine lake in Deschutes County in the U.S. state of Oregon. It lies between the Middle Sister and South Sister volcanic peaks at about 7,000 feet (2,100 m) above sea level in the Three Sisters Wilderness of the Cascade Range. The Camp Lake Trail skirts the lake along its north shore.
The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon. They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California. Each over 10,000 feet (3,000 meters) in elevation, they are the third-, fourth- and fifth-highest peaks in Oregon. Located in the Three Sisters Wilderness at the boundary of Lane and Deschutes counties and the Willamette and Deschutes national forests, they are about 10 miles (16 kilometers) south of the nearest town, Sisters. Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall, occasional rain, and extreme temperature variation between seasons. The mountains, particularly South Sister, are popular destinations for climbing and scrambling.
The Willamette National Forest is a National Forest located in the central portion of the Cascade Range of the U.S. state of Oregon. It comprises 1,678,031 acres (6,790.75 km2). Over 380,000 acres (694 mi2, 1,540 km2) are designated wilderness which include seven major mountain peaks. There are also several National Wild and Scenic Rivers within the forest. The forest is named for the Willamette River, which has its headwaters in the forest. The forest's headquarters are located in the city of Springfield. There are local ranger district offices in McKenzie Bridge, Detroit, Sweet Home, and Westfir.
Bend Glacier is in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation around 8,000 feet (2,400 m). Bend Glacier is just to the north of Broken Top, an extinct stratovolcano.
Black Crater is a shield volcano in the Western Cascades in Deschutes County, Oregon. Located near McKenzie Pass, the volcano has a broad conical shape with gentle slopes. The volcano likely formed during the Pleistocene and has not been active within the last 50,000 years. Eruptive activity at the volcano produced mafic lava flows made of basaltic andesite and olivine basalt; it also formed a number of cinder cones. A normal fault occurs on the western side of the volcano, trending north–south. The volcano has been eroded by glaciers, which carved a large cirque into the northeastern flank of the mountain, forming its current crater.
Carver Glacier is in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation near 7,500 feet (2,300 m), just east of Skinner Glacier. Carver Glacier is on the north slopes of South Sister, a dormant stratovolcano.
Crook Glacier is located in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation between 8,700 and 8,000 feet (2,700 and 2,400 m), nestled within a cirque to the immediate south of Broken Top, an extinct stratovolcano.
Diller Glacier is located in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation average of 9,000 feet (2,700 m) and is on the southeast slopes of Middle Sister, an extinct stratovolcano.
Doris Lake is a natural body of water in the Three Sisters Wilderness of the central Cascade Range in the U.S. state of Oregon. At 5,300 feet (1,600 m) above sea level, the lake is part of a volcanic landscape 27 miles (43 km) southwest of Bend and about 3 miles (5 km) by trail west of the Cascade Lakes Scenic Byway.
Eugene Glacier is located in the US state of Oregon. The glacier is situated in the Cascade Range at an elevation generally above 9,000 feet (2,700 m) and is east of Lost Creek Glacier. Eugene Glacier is on the northwest slopes of South Sister, a dormant stratovolcano.
Irving Glacier is located in the US state of Oregon. The glacier is situated in the Cascade Range at an elevation near 7,500 feet (2,300 m) and is on the south slopes of Middle Sister, an extinct stratovolcano.
Mink Lake is the second-largest wilderness lake in the US state of Oregon. Mink Lake lies at about 5,000 feet (1,500 m) above sea level on a Cascade Range lava plateau in the Three Sisters Wilderness in eastern Lane County. One of many lakes in the Mink Lake Basin, it covers 139 acres (56 ha).
Skinner Glacier is in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation near 8,000 feet (2,400 m), just west of Carver Glacier. Skinner Glacier is on the north slopes of South Sister, a dormant stratovolcano.
Upper Chush Falls is a 200-foot (61 m) waterfall on Whychus Creek, in the Cascade Range southwest of Sisters in the U.S. state of Oregon. Chush Falls, a 50-foot (15 m) waterfall, is further downstream on the same creek. Lying between Chush and Upper Chush is a third waterfall, The Cascade. These and several other falls on tributaries in the vicinity are within the Three Sisters Wilderness. The Northwest Waterfall Survey lists the fall's average flow at 40 cubic feet per second (1.1 m3/s). The highest flows occur between May and August.
Villard Glacier is in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation between 9,000 and 8,000 feet (2,700 and 2,400 m). It is on the northeast slopes of North Sister, an extinct shield volcano.
Williamson Mountain, elevation 6,304 feet (1,921 m), is a peak in the Cascade Range in the U.S. state of Oregon. It is named after Lt. Robert S. Williamson, who with Lt. Philip Sheridan took part in the Pacific Railroad Surveys in central Oregon in 1855. The United States Board on Geographic Names approved the name in 1931. Before that, the peak was known by its Chinook Jargon name of Leloo Mountain (Wolf Mountain), derived from the French le loup (the wolf).
Hayden Glacier is located in the US state of Oregon. The glacier is situated in the Cascade Range at an elevation between 8,800 and 7,800 feet (2,700 and 2,400 m). It is to the northeast of Middle Sister and south of North Sister, both of which are extinct volcanoes.

Linton Falls, is a multi-step waterfall of 8 tiers located in the heart of the Three Sisters Wilderness, just east of the North Sister volcano on Oregon Route 242 in Lane County, in the U.S. state of Oregon. It totals 615 feet fall in eight drops, the tallest and last drop is 85 feet.
Proxy Falls, also known as Lower Proxy Falls, is a cascade and plunge waterfall from a collection of springs on the shoulder of North Sister, that plunges into a gaping canyon near McKenzie Pass in the Willamette National Forest, near Belknap Springs, Oregon. The waterfall is notable for its main drop of 226 feet (69 m) which makes it one of the highest plunge waterfalls in Oregon.

Access to Chush Falls is from Forest Service Road 16, south of Highway 242. The trail to the falls ends at the canyon rim overlooking the falls, but unmarked paths lead down to the base of the waterfall.
