Barker Dam, also known as the Big Horn Dam, is a water-storage facility located in Joshua Tree National Park in California. The dam was constructed by early cattlemen, including CO Barker, in 1900. It was raised in 1949 by rancher William F. Keys. It is situated between Queen Valley and the Wonderland of Rocks near the Wall Street Mill. It is a gathering place for desert wildlife, including many species of birds and Desert Bighorn Sheep. Visitors can reach the dam via a short trail from a nearby parking lot and can see Native American petroglyphs a short distance to the west. There is also good bouldering on side trails near the dam. The park offers a Barker Dam Nature Hike led by a ranger. The lowest nine feet of the dam, the original portion, was constructed of concrete surfaced with stone on the downstream side. The height of the dam was raised an additional six feet with concrete in 1949-1950. The dam has several indentations. An inscription at top reads: "Big Horn Dam Built by Willis Keys, W.F. Keyes, Phyllis M. Keys, 1949-1950." ==Hiking trails== The Barker Dam Loop trail is round trip and has little elevation gain. It goes from the parking lot at Barker Dam, past the dam and several good boulder climbing areas and a wall of petroglyphs. The trail offers good birding near the lake and at several spots along the trail that are surrounded by brush. It is a popular trail and is crowded midday. As of February of 2013 the dam was closed to public access due to numerous instances of graffiti and carvings on the dam itself, but is since reopened. Barker Dam is listed on the National Register of Historic Places. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Barker Dam (California)」の詳細全文を読む スポンサード リンク
