Down by Darby they got some snow on the pass.
I think you only crossed the divide twice, Flesher Pass and then Rogers Pass. Continental Divide goes down west side of Helena, to Butte, then along the west side of the Yellowstone Part through the Tetons. You crossed a couple nice passes.
I think you are too used to the little hills you play around on out east; every speed bump is another pass.
Wind is one of the hazards on the east side of the Rockies.
Glad you made it St Mary in one piece.
