This Red Bus will drive from the East Glacier Hotel around the South end of Glacier Park to Whitefish and the West Entrance because the tour up the Going-To-The-Sun road starts at Lake McDonald.
The road takes its name from the mountain of the same name. The NPS says this about the name:
Local legend, and a 1933 press release issued by the Department of the Interior, told the story of the deity, Sour Spirit, who came down from the sun to teach Blackfeet braves the rudiments of the hunt. On his way back to the sun, Sour Spirit had his image reproduced on the top of the mountain for inspiration to the Blackfeet.
Lake McDonald lies just inside the West Entrance.
And then the road starts to climb, seriously.
Seen from the road, Birdwoman Falls drops 492 feet from a hanging valley. The NPS says that the glaciers of Glacier Park will be gone (melted away) by 2030.
The Blackfeet called the land here the “Backbone of the World”. It’s hard to improve on that.
