WEST GLACIER – There’s still no sign of a man who went missing in Glacier National Park last week.

The last confirmed sighting of Mark Sinclair was on the Highline Trail by a visitor late on the afternoon of July 8, between Haystack Butte and Granite Park Chalet.

He was observed earlier that afternoon by Logan Pass Visitor Center staff as he left an unsecured vehicle, keys, and dog in the Logan Pass Parking Lot and headed towards the Highline Trail.

Glacier National Park spokeswoman Lauren Alley says ground and air crews continue to search the Highline Trail and Granite Park Chalet vicinity, in addition to other drainages and trails near the area.

Crews have encountered steep, treacherous terrain, high winds, rain, and bears, among other hazards making it more difficult to pinpointing Sinclair’s whereabouts, according to Alley.

Additionally, the park closed the Highline Trail from Logan Pass to Granite Park Chalet because a sub-adult grizzly bear was charging visitors and remaining in close proximity to search teams for extended periods of time.

Visitors hiking in the general Logan Pass and Granite Park area may hear search crew whistles, and will see helicopters inserting ground search crews and conducting aerial surveillance.

Alley says in a news release that while search team investigators have received an abundance of information about Sinclair from the public, but nothing has been discovered to reveal his whereabouts.

Search managers expect to suspend large scale ground search efforts later this week unless something substantive is discovered.

Investigations into Sinclair’s activities, personal connections, and information received via the tip line (406) 888-7077 will continue.

The search team is also distributing an updated photo of Sinclair that reflects his most recent appearance.
