Hyalite is a state park located 15 miles south of Bozeman off of South 19th Avenue. The City of Bozeman and park service now plow the infamous road, so park goers have access year round.
The way to the park has a history of capturing motorized vehicles in its snow banks and ruts. I remember my son talking about Hyalite; it was a common gathering place for college students who love the outdoors. It is where he went ice climbing.
