This picture is to the northwest. Although it is lost in the smokiness of the distance, at the far end, there are yet more mountains that formed the northwest end of Lake Missoula. Keep in mind, too, that these pictures were taken from what would have been an island and none of them show the valley in the south, southeast, or southwest of the NBR. Saying that the lake was enormous is vastly understating it.
This is fascinating and did you climb down the slope for fun
No, it isn’t allowed. Too many bison, grizzly bears, etc.
