Answered: Hyalite Creek is just outside Bozeman in Custer Gallatin National Forest. Which state is this?

For many visitors, Custer Gallatin is a gateway to Yellowstone National Park, but it offers plenty of charms itself. Once two separate forests, since 2014 Custer and Gallatin have been managed as one, with a central hub in Bozeman. Stretching across more than 3 million acres, it’s one of the most ecologically diverse areas in the Rocky Mountain region.
