What are known in Jackson as the "Shane cabins" are located on the Gros Ventre road just not too far from the small hamlet of Kelly, Wy. They have more trees around them than the pictures you posted, but perhaps because of the passage of time? Can't tell if they are the same as the ones you posted. I don't really know if they are truly from the film, but it's the common name for these dilapidated cabins.
I've see trees change the landscape over time in other places as well.
SD has the Stratobowl, where high altitude balloons were launched beginning with the Explorer I and Explorer II in 1934 and 1935.
The Stratobowl was also used for eleven Stratolab launches in 1956, 1958 and 1959, as well as one launch in 1959 and four launches in 1965 for cosmic ray studies.
It was also the site of the round the world balloon attempts in 1982 and 1996.
I had visited the site in the mid 1970s and it was still very much preserved as a balloon launch site. I went back and visited the site 30 years later and the bottom of the bowl was just meadow with several good sized pines growing in it.

I also visited the Wright Brothers National Memorial at Kitty Hawk.
Between the 60 ft granite monument built on top of Kill Devil Hill in the 1930s, and the grass, shrubs and in particular trees planted around the perimeter of the site to "protect" the dunes, the site no longer looks anything like it did in 1903.
In fact, if it looked that way then, the Wright Brothers would have went somewhere else as it would have been totally unsuitable for their needs. In their effort to save history, they totally destroyed it.
