Lemei Rock is a shield volcano, and part of the polygenetic Indian Heaven[3] Volcanic Field in Washington, United States. It is located midway between Mount St. Helens and Mount Adams, and dates from the Pleistocene and Holocene. Lemei Rock is the highest point at 5,925 feet (1,806 m).

Geographical setting[edit]

Lemei Rock is the highest peak the Indian Heaven Wilderness in Washington and the Cascade Range. Lemei Rock has a topographic prominence of 2405 ft (733 m).[4] On clear days hikers can see views of four nearby volcanoes: Mount Adams, Mount Hood, Mount St. Helens, and Mount Rainier. The shield volcano is topped by a volcanic crater. While the crater rim is free of snow and ice, snow tends to linger on the summit well into July. A small crater lake by the name of Lake Wapiki, occupies the crater below the Lemei Rock high point. The Lost and Dry Creeks flow off of the southeast side of Lemei Rock and join the White Salmon River, while the Smokey, Little Goose, and Cultus flow from the east and northeast side, and joins Trout Lake Creek, which then discharges into the White Salmon River at Trout Lake. The Rush Creek flows from the west side of Lemei Rock and joins the Lewis River between the Lower Lewis River Falls Recreation Area and the Swift Reservoir.

Geology[edit]

Lemei Rock is one of the many shield volcanoes topped by cinder cones and spatter cones that make up the Indian Heaven Volcanic Field. About 60 eruptive centers lie on the 19-mile (30 km) long, N10°E-trending, Indian Heaven fissure zone. The 230 square miles (600 km2) field has a volume of about 20 cubic miles (100 km3) and forms the western part of a 770-square-mile (2,000 km2) Quaternary basalt field in the southern Washington Cascades, including the King Mountain fissure zone along which Mount Adams was built.

Lemei Rock in the Indian Heaven Wilderness Visitor and Location Map

Popular fishing and hiking destinations in the volcanic field around Lemei Rock include the Indian Heaven Wilderness, which is rather popular for the high mountain meadows among its scattered volcanic peaks. The Pacific Crest National Scenic Trail passes north/south through the volcanic field and the Indian Heaven Wilderness, which is known for its many lakes and spectacular views of four nearby volcanoes: Mount Adams, Mount Hood, Mount St. Helens, and Mount Rainier. It is also known to hikers for an intense population of mosquitoes throughout the summer.[citation needed] Major trails at Lemei Rock are the Lemei Trail, which climbs up the east side of Lemei Rock; and Wapiki Trail, which descends from the Lemei Trail to the deep blue Wapiki Lake, the "crater lake" of Lemei Rock. The Filloon Trail departs from the rustic Little Goose Campground and meets up with Lemei Trail before Lake Comcomly.

The popular fifty-site Cultus Creek Campground, a favorite pastime with berry pickers,[5] is located right at the edge of the Indian Heaven Wilderness. Cultus Creek Campground offers visitors two major trail heads (Indian Heaven Trail #33 and Cultus Creek Trail #108) and popular huckleberry picking access to the Indian Heaven Wilderness,[5] famous for its huckleberries,[5][6] and the volcanic field in which it resides.
