You really can't count on anything at Glacier, we've been there 3 times and have never been all the way across Going to The Sun Road, 1st time we were there the last week of June, the road wasn't opened till the 4th of July IIRC, Second time we went from Two Medicine CG to Logan Pass, the the next day we were moving to the West side and going to do the rest of the road from there, but about 5 mile from the pass, we were turned back due to fires. 3rd time we were early again, (for a different reason) and of course road wasn't open yet.
