UPDATE: The photographer has been found and is safe.
The Ouray Police Department is asking for the public's help in searching for a missing insulin-dependent photographer named Rafael Calderon.
Calderon told his friends he was leaving Leadville at about 11:40 AM on Monday to meet up with them around sunset at the Dallas Divide near the town of Ridgway. Friends became concerned when the photographer never showed up.
"He never showed up" said friend and fellow photographer Lars Leber in a post on Instagram. "I figured he found something else to photograph but he has not been online since or replied to any messages or calls."
According to an official release, Calderon drives a Green Chevrolet Van with a Colorado license plate of MOK-787.
The group also had plans to photograph the Milky Way that evening.
The Dallas Divide is a mountain pass located in the southwest corner of the state near the towns of Ridgway and Placerville. The 8,983-foot pass is situated between the San Juan Mountains and the Uncompahgre Plateau.
Anyone with information is asked to contact dispatch at 970-249-9110.
