St Anthony Sand Dunes

Natural Attraction

Starting about eight miles west of St. Anthony are the living sand dunes - 41,000 acres of exciting potential playground just being discovered by dune buggy and snowmobile enthusiasts.

The white rolling hills of sand range in height from 200 to 300 feet above the 4,900 foot valley floor. They stretch about 35 miles in length and from one to five miles in width. In mid-summer, although the sand gets hot, the temperature rarely tops 90 degrees. The dunes gain in size to a certain point, depending on the intensity of the prevailing winds as they creep slowly north.
