Johannesburg Mountain is one of the most famous peaks in the North Cascades of Washington state. Though not one of the top 100 peaks in the state by elevation, nor one of the top peaks as ranked by topographic prominence, Johannesburg is notable for its large, steep local relief, and particularly its immense, dramatic Northeast Face, which drops 5,000 feet (1,525 m) in only 0.9 miles (1.4 km). The name "Johannesburg Mountain" comes, through an error, from "Johnsberg," the name of three mining claims on the north face of the peak. It has also been called "Elsbeth."
