The hikers from Salt Lake City have been in the Superstition Mountains since at least Sunday, and possibly nearly a week. Maricopa County sheriff's officials say rescue workers braved triple-digit temperatures for a fourth day of searching Wednesday. Searchers reportedly have covered more than 100 miles so far.
Family members say 67-year-old Curtis Meriworth, 62-year-old Ardean Charles and 51-year-old Malcolm Meeks planned on hiking into the mountains and exploring the area about 40 miles east of Phoenix during the day and spending nights in a motel. Their vehicle was found Sunday, parked at a trailhead.
Treasure hunters have been looking for the Lost Dutchman mine for more than a century.
