Columbia Hills State Park (which includes the Horsethief Lake area and Dalles Mountain Ranch area) is a 3,338-acre camping park with 7,500 feet of freshwater shoreline on the Columbia River. Horsethief Butte dominates the skyline. It stands over the lake like an ancient castle. The lake itself is about 90 acres in size and is actually an impoundment of the Columbia River. The lake was flooded into existence by the reservoir created by The Dalles Dam..Horsethief Butte is a very popular rock-climbing location. Two areas are signed "no climbing" for cultural resource protection. NOTE: Climbers are directed to limit their use of chalk when climbing at the butte.... History.For centuries, the park was the site of a Native American village. The Lewis and Clark expedition camped at the village and described its wooden houses in one of their journals. The village was flooded by the waters of The Dalles Dam...Oral history states that the park received its former name -- Horsethief Lake State Park -- from workers in the U.S. Army Corps of Engineers who developed the site. The workers thought the terrain was similar to that of horsethief hideouts in popular 1950s Hollywood westerns. The abundance of horses kept on the premises by local Indians apparently gave the workers their inspiration...The commission combined the park with Dalles Mountain Ranch and renamed the area Columbia Hills State Park in 2003... Special.The park contains Native American pictographs (paintings) and petroglyphs (carvings). Some of the oldest pictographs in the Northwest are found in this park.
