What about the mountain pictures in Ennis and Alma's houses? One hideous one in the first cabin, which reappears on the kitchen wall of the Riverton apartment - it's a ghastly pseudo-Mediterranean pseudo-oil thing, the sort you get ( used to get? - haven't been in one for a while) in cheap motels, but they evidently liked it enough to keep it. Then there's a different one on the wall of Monroe's house, seen just as Ennis leaves after his final confrontation with Alma. How odd that she should have in front of her throughout her marriage a reference to the one place where Ennis had found love.
