WEST GLACIER – Glacier National Park officials are scaling down their search efforts for a man who vanished more than a week ago.
The investigation into the disappearance of Mark Sinclair, 66, of Whitefish, will continue, however, as park officials said they are still looking for clues as to where he might be.
Sinclair was last seen on Monday, July 8 near Logan Pass and the Highline Trail. The overall search area encompassed numerous drainages east and west of the Continental Divide including Upper McDonald Creek, Mineral Creek, Swiftcurrent, and Belly River drainages.
Glacier National Park spokeswoman Lauren Alley said trails and off-trail search areas have included Flattop Mountain, the Highline from Logan Pass to Goat Haunt, Swiftcurrent Pass, the Loop, and Hidden Lake.
Officials said searching will continue, but in a limited capacity.
“We continue to ask the public to think back to their visits to the park last week. Additional sightings or the discovery of Mark’s belongings could help investigators identify new search tactics,” said Search Team Commander Ed Visnovske.
Weather and difficult terrain have hampered efforts to find Sinclair, according to Alley.
Sinclair was last seen at approximately 2:30 pm on July 8 by Logan Pass Visitor Center staff departing the parking lot towards the Highline Trail. He left behind his dog, unsecured vehicle, and car keys. He was wearing all gray or nondescript clothing (possibly in shorts), a yellow bandanna around his neck, a gray waist fanny backpack, and no hat. His hair is completely white and he may have a beard that is white as well. He is 5’8’’ and approximately 155 lbs.
