lava flow of Lava Butte. The cinder cone was also exploited to some extent for its economic value. In June 1926, a quarry was developed in the fault scarp east of Lava Butte as a source for paving material for the first The Dalles-California Highway (later U.S. Route 97). In November 1929, cinders from Lava Butte were shipped to Longview, Washington, to be used in construction of Longview Bridge across Columbia River. A United States Forest Service fire lookout tower was built on the summit in 1931, and in early 1933 a steep, single-lane road was constructed spiraling up to the summit. In February of that year, the local Skyliners ski club proposed a ski jump on Lava Butte, but it was never built. In June 1946, widening of the road up Lava Butte to two lanes was completed, along with constructing two small parking lots at the summit. The road was later paved in July 1950. The original lookout was replaced with a larger one in 1957, which was subsequently enlarged in 1962 to accommodate a small visitor center and museum on the first floor. In 1998 this was replaced with a new lookout built in the original L-4 style of 1931. In July 1966, twenty-two astronauts trained in Central Oregon for the upcoming Moon landings, at sites including Lava Butte, Lava River Cave, and Newberry Crater. In May 1967 the U.S. Forest Service created the Lava Butte Geological Area to protect the cinder cone, with plans for recreational and interpretive development. Construction of the Lava Lands Visitor Center located just south of the cone began in April 1969 and it was finally dedicated in September 1975. In November 1990, Newberry National Volcanic Monument was created encompassing Newberry Crater, Lava Cast Forest Geological Area, Lava River Cave, and the Lava Butte Geological Area. From early May to mid October, a shuttle transports visitors up Red Cinder Road from the Lava Lands Visitor Center to the lookout on Lava Butte. Hiking up Red Cinder Road is a year-round option. A scenic rim trail around the top of Lava Butte is long.
