WINONA, Minn. — After extensive searching in Yellowstone National Park, Austin King, a Winona native and concession employee at the park, remains missing. The park said “limited search efforts” will continue as the search turns to recovery. “I haven’t given up on the impossible,” Brian King-Henke, Austin’s father, wrote on the family’s GoFundMe page on Wednesday, Oct. 2. “Please stay strong for him and keep him in your prayers.” Austin King last spoke with a family member on Sept. 17, from the top of Eagle Peak, which is in the park’s “remote southeast corner,” according to the park. Eagle Peak is the highest point in the park at 11,372 feet. King, 22, is described as a white male who is 6 feet and 160 pounds with brown hair and hazel eyes. He was last seen wearing glasses, a black sweatshirt and gray pants. “Despite significant search efforts over the past week and a half, we have not been able to locate Austin,” Yellowstone National Park Superintendent Cam Sholly said in a statement. “Although we will continue to hope for the best, I want to extend my deepest sympathies to Austin’s family, friends and colleagues. I also want to thank the teams from Yellowstone and Grand Teton national parks, and Park and Teton counties, Wyoming, who have all worked tirelessly to find Austin in some of the most difficult and remote terrain in Yellowstone.” The searchers “have not found any definitive clues as to King’s current whereabouts,” the park said in a Facebook post on Wednesday. King had camped in the upper Howell Creek area. On a planned seven-day hike to summit Eagle Peak, King noted fog, rain, sleet, hail and windy conditions on the summit. He was reported “overdue” to the Yellowstone Interagency Communications Center on Sept. 20, when he did not arrive for a boat pickup near Yellowstone Lake’s Southeast Arm. The search efforts, which started on Sept. 21, have included more than 100 personnel and helicopters, a drone, ground searchers, and a search dog team near Eagle Peak, according to the park. The park described the area as “high-elevation, expansive and hazardous.” The searchers reported snow, ice and 6-foot drifts, the park said in a Facebook post on Sept. 24. People with information about King’s whereabouts can contact the Yellowstone Interagency Communications Center at 307-344-2643. “Each everyone who has opened their hearts to us we are eternally in your debt,” Brian King-Henke wrote. “I am honored by your kindness.”Related Articles Outdoors | Margaret Crimmins Mason: Looking for joy?
