We made it to Three Forks (near Bozeman) on mostly dry roads with only some fog to contend with. But then the forecast turned into storm warnings with travel not recommended. We thought about staying in Three Forks but it looked like the weather would hold off till Idaho Falls. We were lucky and the heavy wet snow didn't start till just as we arrived.
The storm was supposed to end in the night and we hoped to get moving again in the morning, but the warnings were continued till the afternoon so we decided to stay another night. By noon the snow had stopped and we could get outside to check out the namesake falls.
