PINEDALE, WY — A 55-year-old Missouri hiker was found alive after spending five days missing in Wyoming’s Wind River Range, ending an extensive search that involved ground crews, helicopters and drone support. Shaun Mackelprang was reunited with his family on Wednesday, Aug. 26, after rescuers located him near Scott Lake in the backcountry.
Authorities said Mackelprang was dehydrated when teams reached him, but he survived the ordeal. He had started his trek on Aug. 20, heading toward Gannett Peak from the Green River Lakes Trailhead. His recovery came six days after he set out for Wyoming’s tallest peak, which rises to 13,804 feet.
Search crews used air and ground teams to cover the remote Wind River backcountry
Tip Top Search and Rescue and the Sublette County Sheriff’s Office led the operation after Mackelprang was reported missing. Searchers worked from both the ground and air, with the sheriff’s office drone team assisting Tip Top’s helicopter from above.
Crews eventually found him alive in the vicinity of Scott Lake. A ground team prepared him for transport, and a helicopter extracted him from the backcountry at 9:45 a.m. on Wednesday. Officials said the terrain made the operation difficult, but the coordinated search brought the man out safely.
Sublette County Sheriff KC Lehr described the outcome as “a miraculous recovery” and said Mackelprang had placed himself in the best position to be rescued after a bad situation.
A summit register entry helped narrow when something went wrong
Investigators and rescuers said Mackelprang’s signature in the register at the top of Gannett Peak played a key role in the search. That entry helped crews narrow the timeframe for when he may have run into trouble during the trip.
Lehr said the detail showed why trailhead and summit registers matter, because hikers can sometimes provide the information that later helps searchers locate someone in distress. He said the case also highlighted how even brief contact with another hiker can become critical if that person later goes missing.
The sheriff called the rescue a national effort, not just a local one, and said the register entry was one reason the operation succeeded.
Mackelprang thanked rescuers from his hospital bed in Pinedale
After the rescue, Mackelprang wrote from his bed at Sublette County Hospital in Pinedale that he could not praise the search teams enough. He thanked the men and women who worked to save his life and said their willingness to help strangers reflected “the goodness of the human heart.”
He also singled out Tip Top Search and Rescue and the Sublette County Sheriff’s Office, saying they were ready and prepared to stand up for him when he needed help. Mackelprang said it is no easy task to put your life on the line for someone else, especially for a stranger.
His comments underscored the size of the rescue effort and the personal gratitude felt by his family after five days of uncertainty.
Family members credited volunteers and hikers who shared crucial tips
Mackelprang’s brother, Romel Mackelprang, posted a message on the sheriff’s office Facebook page thanking everyone involved. He said the Tip Top team and sheriff’s department members were true heroes and stressed that every team member played a role in finding Shaun.
Romel also pointed to other hikers who saw Shaun on the trail or later called from home to share information that helped narrow the search area dramatically. He said those tips made a major difference in focusing crews on the right part of the wilderness.
The sheriff’s office echoed that appreciation and publicly thanked a list of hikers from several states, including Tennessee, Utah, South Carolina, Ohio, Washington, Vermont, Wyoming, Colorado and Idaho.
Sheriff says the rescue shows why trail information can save lives
Lehr said several of the hikers had spoken with Mackelprang, encountered him on the trail or shared details that allowed rescuers to tighten the search window. Without that information, he said, the outcome might have been different.
He also praised the Mackelprang family, saying they were a testament to what family, love and faith should be about. The comments reflected how the rescue became more than a single backcountry operation and turned into a wide network of support.
For deputies and volunteer rescuers, the case became a reminder that preparation, communication and trail records can make the difference between a prolonged missing-person search and a live recovery.
