Twenty-two year old Morgan Heimer remains missing on the Colorado River within Grand Canyon National Park; and a six day search by the National Park Service has turned up no additional clues as to his whereabouts.

Heimer was last seen on Tuesday, June 2, at approximately 4 p.m., around River Mile 213 near Pumpkin Springs. Initial park response included searching the last known area by air, and an immediate hasty search by rangers. For the last six days, park rangers have extensively searched the river between River Miles 211-225 and on land stretching from River Mile 211-215.

Heimer is described as a 22-year old male, 6’ tall, blond hair, blue eyes and was last seen wearing a dark-colored Astral personal flotation device, a blue plaid long sleeve shirt, a pair of Chaco flip-flop sandals, a maroon baseball cap, and brightly colored shorts. He was also carrying a purple water bottle with him when he was last seen. Heimer is working as a guide for Tour West. The group was on day six of an eight-day trip when Heimer went missing.

With no additional clues to guide search efforts on land or water, the search will be scaled back to a continuous, but limited, mode in which rangers and pilots will continue to search for clues when in the area. In addition, flyers with Heimer’s picture and description remain posted at various South Rim locations and all launching river trips will be briefed on searching for Heimer.

The National Park Service is currently conducting a Search and Rescue operation. A missing persons investigation is on-going. No further information is available at this time. Any individual with information on the location of Morgan Heimer should contact the National Park Service Tip Line at 928-638-7840.
