FILLMORE, Utah (AP) - Search and rescue crews are looking for a man missing since last week in west central Utah.

The Millard County sheriff's office says 31-year-old Leroy Buckley, of Fort Leonard Wood, Mo., and 44-year-old Kurt Gregory, of Twin Falls, Idaho, hiked to Notch Peak to BASE jump on Wednesday. Gregory lost sight of Buckley along a ledge near the base of the peak.

Gregory searched but couldn't find Buckley and called police using an emergency beacon when he ran out of water. A Utah Department of Public Safety helicopter picked up Gregory on Wednesday.

Crews started an extensive search of the area by ground and air, but Buckley remains missing.

BASE jumpers use a quick-release parachute to jump from mountains, cliffs and buildings.
