Damian and Evan McManus parked their car near Echo Lake in Clear Creek County on April 2. That was the last time they were seen.

The Alpine Rescue Team surveyed a map where several areas had been searched by air and ground.

All trails around Echo Lake have been double checked and not a single clue has been found.

Rescuers said the warm weather hasn’t helped like they hoped it would.

“It’s sort of a double-edged sword. It helps expose some of the tracks but it also destroys some of the tracks. The high winds we’ve had today, yesterday, all day, have blown the snow around. The weather has hurt us more than it’s helped us,” said Alpine Rescue Team spokesman Steve Wilson.

Rescuers said they have been triple checking some of the most likely area the father and son team may have tried to hike through but haven’t found any more clues.

Authorities say Damian McManus, 51, and Evan McManus, 19, who are from St. Louis Park, Minn., were last heard from on Wednesday. They were hiking near Echo Lake on the north shoulder of Mount Evans. The car they were traveling in has been located near the entrance of a campground.

The two men left for a camping trip on Wednesday and were due back on Sunday. They had driven to Colorado from Minnesota and planned to stop and hike along the way as part of their father-son trip for spring break.
