Morgan Heimer, 22, went missing from a commercial rafting trip on June 2, 2015, while guiding with Tour West in the Grand Canyon. He was last seen about 4:00 p.m. standing on a low cliff at the water’s edge near River Mile 213, a spot called Pumpkin Springs, after facilitating a cliff-jumping activity for clients. Heimer was wearing a dark personal flotation device, a blue plaid long-sleeved shirt, brightly colored shorts, Chaco flip-flops, a maroon baseball cap, and carrying a distinctive purple water bottle.

When the lead guide briefly turned away to speak with a client, Heimer was gone; his absence wasn’t noticed until about 7:00 p.m. when he failed to appear for dinner. A satellite call to Grand Canyon National Park at 7:26 p.m. prompted an intensive search. Rangers conducted air and ground searches from River Miles 211 to 225 for six days with no sign of Heimer. The active search was then reduced to continuous patrols, flyers were posted, and incoming river trips were notified. No clues to his whereabouts have been found.

Does anyone who was on or near that stretch of river in early June 2015 remember seeing Morgan or his purple water bottle?
