Wallowa Mountains

The Wallowa Mountains are a mountain range located in the Columbia Plateau of northeastern Oregon in the United States. The range runs approximately 40 miles (64 km) northwest to southeast in southwestern Wallowa County and eastern Union County between the Blue Mountains to the west and the Snake River to the east. The range is sometimes considered to be an eastern spur of the Blue Mountains, and it is known as the "Alps of Oregon". Much of the range is designated as the Eagle Cap Wilderness, part of the Wallowa–Whitman National Forest.

Lower Monumental Dam Dam in Franklin and Walla Walla counties, Washington, U.S.

Lower Monumental Lock and Dam is a hydroelectric, concrete, run-of-the-river dam in the northwest United States. Located on the Snake River, it bridges Franklin and Walla Walla counties in southeast Washington. It is six miles (10 km) south of Kahlotus and 43 miles (70 km) north of Walla Walla.

Ice Harbor Dam Dam in Franklin / Walla Walla counties, Washington

Ice Harbor Lock and Dam is a hydroelectric, concrete gravity run-of-the-river dam on the Snake River in Walla Walla and Franklin counties in the U.S. state of Washington. The dam is located 8 miles (13 km) northeast of the town of Burbank and 12 miles (19 km) east of Pasco, river mile 9.7. Its name comes from a tiny bay in the river where boats once tied up to wait for upstream ice-jams to break up.

Stakkastadvatnet

Stakkastadvatnet is a lake on the border of Rogaland and Vestland counties in Norway. The 2.92-square-kilometre (1.13 sq mi) lake mostly lies in Rogaland along the municipal borders of Haugesund and Tysvær. A very small portion of the northern part of the lake crosses over into the municipality of Sveio in Vestland county. The lake lies about 6 kilometres (3.7 mi) northeast of the town of Haugesund. The lake has a small dam on the northwestern edge of the lake. The natural outlet of the lake flows through the dam and into the nearby lake Vigdarvatnet, located to the north.

Sacagawea

Sacagawea was a Lemhi Shoshone woman who, at age 16, helped the Lewis and Clark Expedition in achieving their chartered mission objectives by exploring the Louisiana Territory.

Sacajawea Patera

Sacajawea Patera is a large, elongate caldera located in Western Ishtar Terra on the smooth plateau of Lakshmi Planum, on the planet Venus. The image is centred at 64.5 degrees North latitude and 337 degrees East longitude. It is approximately 420 km (260 mi) wide at the base. Sacajawea is a depression approximately 1–2 kilometres deep and 120 x 215 kilometres in diameter; it is elongate in a southwest-northeast direction. The depression is bounded by a zone of circumferential curvilinear structures interpreted to be graben and fault scarps. These structures are spaced 0.5–4 kilometers apart, are 0.6–4.0 kilometers in width and up to 100 km (62 mi) in length. Extending up to approximately 140 km (87 mi) in length from the southeast of the patera is a system of linear structures thought to represent a flanking rift zone along which the lateral injection and eruption of magma may have occurred. A shield edifice 12 km (7.5 mi) in diameter with a prominent central pit lies along the trend of one of these features.

Columbia Plateau Trail

The Columbia Plateau Trail is a 130-mile-long (210 km), 20-foot-wide (6.1 m) corridor in eastern Washington state maintained as part of the Washington State Park system. The trail runs along the abandoned right-of-way of the former Spokane, Portland and Seattle Railway from Cheney to the confluence of the Snake and Columbia rivers at Pasco, Washington, passing through five counties in the southeastern part of the state. The trail is mostly gravel, except for a 3.75 mile portion between the Cheney and Fish Lake trailheads. Recreational uses include hiking, mountain biking, horseback riding, in-line skating on paved portions, and wildlife viewing. The close proximity of the railroad to the paved portion makes this section of the trail a popular spot for railfanning.

Windust Caves Archaeological District United States historic place

The Windust Caves are a series of nine caves that have been eroded into the side of a basalt cliff on the north side of the lower Snake River. The caves were excavated from 1959 until 1961 by a crew led by Harvey S. Rice. Some of the caves had been disturbed, though also somewhat preserved from looting by collectors, by rock falling off the roofs of the caves during construction of the Northern Pacific Railway. Other caves were damaged by collectors. In 1961, upon completion of the Ice Harbor Lock and Dam, the caves were flooded by the reservoir known as Lake Sacajawea.

Strandavatnet

Strandavatnet is a lake in Hol municipality, Norway. The lake covers an area of 23.75 square kilometres (9.17 sq mi), and lies 975 metres (3,199 ft) above sea level.' The lake is a reservoir for the Rud hydroelectric powerstation in Hovet, Buskerud. In 1952/1953 a dam was constructed which lifted the lake level 28 meters, thus the lake varies between 950 and 978 m above sea level.

Sacajawea State Park
