Earl Guss Park is a Yellowstone County park on Alkali Creek. It lies between the upper Metra parking lot, Main Street, and the Yellowstone River in Billings Heights. Earl Guss Park has a waterfall that is man-made, but decades have passed since it was created. Folks could easily mistake it for a natural waterfall! Upper Guss Park has picnic shelters and quiet trails below the noise of Main Street.
