Wye in a loop

[Sumpter250]

There is no wye. The crossing trail is just that, a vehicle path, and there are no turnouts or track in that image to make a wye out of anything, just a loop that is clearly delineated. Expand the image and you'll see it more clearly.

I have to agree. Expanding the image clearly shows only a loop, with no other tracks, or turnouts.

Could there have been a wye there at one time? Maybe, but then again, would a railroad go through the expense of removing the now unused track? The photo clearly shows no "unused track".
Could a wye have been replaced with a loop? That is a possibility, in that a loop turns a train more efficiently than a wye, and there is, what appears to have been, where a wye might have existed. Clearly though, only a loop exists there now.
Geographically this is in Glacier National Park, in Northwest Montana. near the town of Summit, about thirty miles East of Kalispell
