Deadwood

Deadwood is a small town on Earth located in western South Dakota, which is part of the United States of America. The community near the Black Hills region of the state.

A 19th century version of Deadwood was the setting of a holodeck program that Lt. Worf, Alexander, and Counselor Troi once participated in. In this program, Worf portrayed the local Sheriff who had recently arrested the outlaw Eli Hollander. There was a computer malfunction while the program was running. As a result all the characters were replaced with duplicates of Lt. Commander Data - complete with his speed, strength, and accuracy - and the holodeck safeguards were turned off.
