LARIMER COUNTY, Colo. (CBS4)- Park rangers at Rocky Mountain National Park have rescued two hikers.

The first hiker, William Pinch III, 51, of Arvada, became separated from his family near the campground at Sandbeach Lake in the Wild Basin region of the park on Friday.

He was reported missing by his family at about 3:30 p.m. on Thursday. Park Rangers began looking for him Friday morning and found Pinch at about 5 p.m. during a search after they heard him blowing a rescue whistle.

Pinch was dried off and warmed up by rescuers on scene. He was able to walk with rangers to the trailhead about 4½ miles away and was taken to Estes Park Medical Center for non-emergency care.

In another incident, rangers at the Longs Peak Ranger Station were notified about 1 p.m. of an injured man on the Estes Cone Trail. At about 2:45 p.m. rangers discovered David Solzman, 78, from Chicago.

Rangers treated his ankle injury onsite and assisted him on horseback to the trailhead. Solzman took himself to the Estes Park Medical Center for treatment.

In both cases park rangers worked through monsoonal rain, hail and lightning to find and rescue the park visitors.
