I really don't have much of an idea what this is. Going off of roughly a straight line or great circle route from Salt Lake City to Seattle using what I estimate the time to be at which we passed over this my best guess is that this is the Wallowas/Eagle Cap Wilderness in NE Oregon. But it could be any number of mountain ranges such as the Strawberry Mtns in OR, Blue Mtns in OR or WA, Sawtooths in ID, Salmon River in ID etc. With some topos and some time I might be able to figure it out but it isn't worth the trouble. The little corner of the plane window in the lower right is quite annoying.
