Nice pics.
I spent a week at ...Bowman Lake (?) upper west part of Glacier park, back in 1993. It was August, probably 90 degress, and the lake was probably 55! Couldn't stay in long. Think about sweating in that heat and then having to wash off a bit in quite cold water!
Best memory, woke up one morning to a grizzley about 100 yards off, toppling trees. He eventually walked thru our campsite about 20 -30 feet from us. Oh, yea, we were in the cab of the truck at that point ready to take off! Good times!
