CLEAR CREEK COUNTY, Colo. - Searchers will be back in the Echo Lake area today looking for a father and son who disappeared one week ago.
Damian McManus, 51, and Evan McManus, 19, left on a camping trip last Wednesday, they haven't been heard from since.
Their vehicle was located Sunday near the entrance of the campground at Echo Lake.
Cell phone data shows the pair's cell phones were "active" until 3 p.m. (for one phone) and 7:20 p.m. (for the other phone) last Wednesday near the Echo Lake Campground, according to Howard Paul with Alpine Rescue. Officials don't know if the cell phone batteries died or if the phones were turned off.
Paul said that information helped searchers concentrate their efforts southeast, south and southwest of the campground Tuesday. However, officials said the cell phone information does not tell them which way the men went.
There are about five trails in the Echo Lake Campground area and many people go off-trail exploring.
The Clear Creek County Sheriff's Office said 50 searchers from nine Colorado Search and rescue teams worked in snow of more than three feet in places and in thick timber on the mountainsides flanking Colorado State Highway 5.
Flight for Life Colorado also searched key areas between 10,000 feet to more than 14,000 feet Tuesday.
"[Searchers] were unable to find any clues as to the McManus’ location," the Sheriff's Office said in a news release.
-- McManuses' trip
The McManuses are from St. Louis Park, Minn. They came to Colorado for a father-son Spring Break trip, friends said. The McManuses were due back on Sunday.
Damian McManus' wife and Evan's twin sister took a mother-daughter trip to Mexico and had just returned on Sunday. When they did not hear from the men on Sunday afternoon, they reported the pair missing.
Echo Lake is 23 miles from Evergreen and 13 miles from Idaho Springs at the base of the Mount Evans Highway.
