Glacier National Park officials say there has been no sign of a 66-year-old man who's been missing for over a week. The trail where he was last seen is closed because of grizzly bear activity.
Mark Sinclair of Whitefish was last seen on the Highline Trail on July 8 after leaving a vehicle with a dog inside at the Logan Pass parking lot.
Searchers on the ground and in the air have turned up no clues about his disappearance.
Park officials said in a statement Tuesday that searchers plan to suspend ground-search efforts this week unless something substantive is discovered.
The Highline Trail has been temporarily closed after a young grizzly bear charged visitors and wandered close to search teams last weekend.
Park spokeswoman Lauren Alley says there is no evidence Sinclair was attacked by a bear.
