A 23-year-old hiker has vanished while scaling the tallest peak inside Rocky Mountain National Park, officials say.
Lucas Macaj of Colorado Springs was last heard from early Sunday afternoon "when he texted a friend indicating that he was on the summit" of the 14,259 ft. Longs Peak, according to the National Park Service.
The NPS says "significant storms moved through high elevations in the park" later that day and Macaj’s vehicle was still parked the following morning at the Longs Peak Trailhead after being reported missing Sunday night.

The search for Macaj has been ongoing, but it was "hampered by strong winds, white-out conditions and low visibility" on Tuesday, the park said.
