The
St. Anthony Dunes are about eleven miles from the town
of St. Anthony in eastern Idaho. Golden-white quartz
sand covers an old basalt lava field in a strip about a
mile wide and thirty miles long. The dunes range in
height from ten feet to over 400 feet, but they never
look the same. The wind that blew the sand to this place
continues to rearrange it.
The
dunes continue to shift, moving about eight feet a year
toward the east. Geologists now know that the wind blew
the sand to this place many thousands of years ago when
Idaho's ancient Mud Lake, about forty miles to the west,
began to dry up. As water receded from the shoreline,
the wind picked up the exposed sand and carried it off.
