These postcards were all issued by the Glacier Park Company, which was owned by the Great Northern. Although GN sold its hotels in 1960, it retained the “Glacier Park Company” name as its real estate division. So these postcards likely date from the 1950s.
This postcard shows Swiftcurrent Lake and Mt. Wilbur. The Many Glacier Hotel is on the east side of Swiftcurrent Lake directly opposite Mt. Grinnell, so most photos of the lake show the view of Grinnell from the hotel grounds. The photographer who took this postcard photo chose to aim the camera a little bit to the north.
This postcard only says it is of an alpine lake without identifying either the lake or the mountain. However, a quick search on the web reveals that it is Hidden Lake looking east towards Reynolds Mountain. The postcard credits the photo to famous Portland photographer Ray Atkeson.
This postcard shows a sign at the summit of the Going-to-the-Sun Highway. The mountain in the background is also Mt. Reynolds, but viewed from the north.
What would a visit to Glacier Park be without a photo, or at least a postcard, of a mountain goat, the Great Northern’s famous logo?
