This is one of 15 photo prints left in a hotel room in Minnesota, date unknown. The photos were rescued years or decades later from the lost and found. The photographer may be Tom Brudos, whose name appears on the photo sleeve. A letter in the same bundle, addressed to Dick Brudos, is dated 1955. I google image searched "flat top mountain Alaska" in an effort to locate this unique chop-top geographic lump - and found a mountain with just that name, but the photos were taken from the terrestrial side and the landscape didn't look smooth and almost "mowed" like this does. So, where is this? Here are more photos from the same excursion. View full size.

Update: JFlash, a Shorpy reader, has identified the geographic location (I incorrectly guessed Alaska) of the flat-top mountain in this photo as Thule, Greenland (and the mountain as "Mt. Dundas"). He suggests that all of the photos may be from Greenland. And I think he may well be right. I'm on a new path now! Thanks for the great info, J.
