those are the Grand Tetons, ... just north of Jackson Hole, and about 1 hour from the west entrance to Yellowstone Ntl Park
you are looking at a southern view of them, ... in a long range, ... in person, ... they average 1300 feet, an you are at 4000
I was born an raised in Idaho for 19 years, .... my family is still all up there, ... I love to make a "pit stop" to Yellowstone/Tetons anytime I am up there
... but how about something closer
