Unfortunately, Montana, like the rest of the West is covered in heavy smoke from the forest fires this summer. When I arrived on Thursday, this is what it looked like at 2:30 in the afternoon:
In addition to smoke, bears are another major concern in Glacier. Highly recommended to hike with bear spray. I only had to grab for mine once as a bear crossed me on a trail, but my campsite had bears in it every night.
Luckily on Friday night there was a decent storm (including snow) that blew the air clear of all the smoke and made for a stunningly crisp, clear Saturday for my hike up to Grinnell Glacier and Grinnell Lake.
No storm, but Saturday night the temperatures plummeted again and my tent was completely frozen in the morning when I woke up. Smoke started coming back into the park, but wasn't nearly as bad as it had been so still had some decent views along the Highline trail.
By Monday the smoke was back in full force and wouldn't clear before I left, but there were still some great hikes and a few moments of blueish skies from time to time.
