Editor's note: This updates with searchers failing to find any trace of the missing man, corrects his age to 39.

Nearly three-dozen searchers, aided by two overflights, failed Saturday to find any clues of a Texas man thought to be missing in the Bear Lake area of Rocky Mountain National Park.

The ground crews hit all major trails around the popular destination without finding any sign of Troy Green, 39, of San Antonio. Their efforts were aided by hundreds of visitors who came to the area for sledding and tubing, park officials said.

The search for Mr. Green at Bear Lake was spurred by the discovery Friday of his rental car at the Bear Lake parking lot, park officials said. A limited search was performed Friday afternoon before fading light and cold temperatures suspended the effort.

On Saturday, 35 searchers were involved in looking for Mr. Green. Rangers were being assisted by Larimer County Search and Rescue and Rocky Mountain Rescue. Two overflights of the area also were conducted in a bid to find the man.

Search efforts were to continue until nightfall, and then resume Sunday morning.

Since Wednesday, there has been continuous winds and snowfall in the Bear Lake area. Accumulation of snow varies based on elevation. At Bear Lake, located at 9,475 feet, there has been 9 inches of new snow since Wednesday, the park reported.

There are numerous trailheads that leave from the Bear Lake area. It is unknown where Mr. Green’s destination was or what kind of clothing he was wearing.

The man was planning to attend a conference in Denver. When his wife did not hear from him on Thursday, she contacted the Denver Police Department. He did not arrive at the conference on Friday.

If anyone was visiting the Bear Lake area of Rocky Mountain National Park on Thursday or Friday, park rangers would like to hear from you. Please call Rocky Mountain National Park at (970) 586-1204.
