Looking over the far northeast end of Lower St Mary Lake to the west. I think we are looking at East Flattop Mtn and behind that to the left is Going to the Sun Mountain. I'm guessing center background is Siyeh and obviously Old Sun Glacier on Merritt with what I think is Apikuni Mountain in front of it (alongside Many Glacier Road). I would see Merritt on my Belly River hike too.
