[1887+; fr the fact that dead or rotten wood does not produce much heat when burned]
city, seat (1877) of Lawrence county, western South Dakota, U.S. Located just northeast of Lead and about 40 miles (65 km) northwest of Rapid City, Deadwood lies in a canyon formed by Whitewood Creek in the northern Black Hills, more than 4,530 feet (1,380 metres) above sea level. Built at the base of the steep wooded inclines of Deadwood Gulch and extending up the hillsides, it was named for the dead trees found in the canyon.
