We spent a total of a day and a half at Glacier National Park, not nearly enough, but we did manage to visit Two Medicine, Many Glacier, and drive along Going-to-the-Sun Road which roughly divides the park into northern and southern halves.
Our first afternoon was sunny but windy, with constantly shifting clouds. Aspens were near their fall colors peak.
The following day started with thick fog and a colorful sunrise near the town of St Mary, the eastern entrance to Glacier National Park.
In the Many Glacier area, the only decent shot I got was one of Lake Sherburne.
Going-to-the-Sun Road was a nice drive, despite the overcast sky. The following two shots give you a taste of what the scenery looked like from the road.
There were many waterfalls along Going-to-the-Sun Road. Even though they did not have as much water as in the spring, they still provided interesting views more appealing than the gloomy sky.
Finally, the highest waterfall in Glacier National Park: Bird Woman Falls. It is named not for Sacajawea, but for the wife of either Old Sun or Lone Walker.
A sign said Bird Woman Falls was 492 ft (150 m) tall, but the World Waterfall Database puts its height at 960 ft (293 m). That height includes an upper drop of 175 ft (53 m) seen near the top of the above photo, a larger tier of 560 ft (171 m), and a number of cascades between the two.
