Its nearest higher peak is Naches Peak, 0.59 mi (0.95 km) to the southeast. Deadwood Peak takes its name from Deadwood Lakes and Deadwood Creek to its northwest, and their names came from the large number of downed trees in the area. From Chinook Pass, a short scramble up the south side leads to the summit with unobstructed views of Mount Rainier.
