Officials with Rocky Mountain National Park announced Tuesday evening that search efforts for 20-year-old Micah Tice, who was last seen in the Longs Peak area of the park Nov. 24, have been suspended.

Very few clues have been discovered during search efforts, according to park officials. During the search, team members have encountered harsh winter conditions including extreme winds, low visibility, bitter wind chills, below freezing temperatures, deep snow and high avalanche danger.

Snowfall and high winds in the extreme high mountain terrain make finding clues to Tice’s whereabouts even more difficult.

In the absence of additional clues, active search operations have been suspended. Limited search activities may occur during winter months if conditions allow, according to the park.

Over a seven-day period, ground and aerial searchers covered an approximate 10-square-mile search area, focused on sections of the Longs Peak Trail, the East Longs Peak Trail, the Battle Mountain area, Granite Pass, Jim’s Grove, the Boulder Field, Mount Lady Washington, Chasm Lake, Peacock Pool, Boulder Brook Drainage, the Storm Pass Trail and the Wind River drainage, according to park officials.

Two Colorado National Guard helicopters from Buckley Air Force Base in Aurora were able to assist with aerial reconnaissance Sunday and search managers focused their efforts on Battle Mountain, the Boulder Field, the Keyhole Route, the south side of Longs Peak, Peacock Pool, Mount Lady Washington, Half Mountain and the upper part of the Roaring Fork Drainage.

Despite the widespread search efforts, there have been so signs of Tice.

The U.S. Air Force Academy requested assistance in locating Tice, who is a cadet candidate after he was last heard from Nov. 24, according to park officials. Tice’s vehicle was located the afternoon of Nov. 26 at the Longs Peak Trailhead, according to officials, though his planned destination was unknown.

Tice is still considered a missing person and the park said it will continue its investigation in hopes of gaining further information.

Park rangers would like to hear from anyone who has been in the Longs Peak area since Nov. 24, or who may have had contact with Tice regarding his planned route on Longs Peak. Contact Rocky Mountain National Park at (970) 586-1204.
