St. Anthony, Idaho

St. Anthony Sand Dunes
Deadhorse Bowl at Saint Anthony Dunes

Name: St. Anthony Sand Dunes aka Saint Anthony

Location: Eastern Idaho, 50 miles northwest of Idaho Falls

Description:

This 10,600 acre playground of clear, shifting, white quartz sand is known for its unique beauty and exceptional recreation opportunities.

Prevailing winds carried the sand from the nearby Teton and Snake Rivers and deposited them as dunes among the hills. These hills were once active volcanic vents pouring great depths of lava over the earth.

Today the St. Anthony Sand Dunes are home to a Wilderness Study Area (see more info below) and one of the largest herds of wintering elk in the United States.

Elevation - 5,000 ft.

  • Sensitive Species and the Resource Conflict
    ORV use of the St. Anthony Sand Dunes has grown dramatically over the past few years. Unfortunately, this use has spurred a noticeable decline in vegetation which is critical to winter land, wilderness quality and sensitive species. Please ride only on the open sand and designated routes. Our goal is to protect the dune’s unique resources and keep the dunes open for your enjoyment. The following species are not listed as threatened or endangered but are species of special concern. Both species do have state conservation assessments and strategies prepared. These documents are available at the BLM office in Idaho Falls . The BLM has conducted inventories to determine the populations and breeding areas for the Dunes Tiger Beetle and the Evening Primrose Flower. We ask that if you do see some of these Evening Primrose plants that you go around them and please do not ride over or through them.

If continued access to St. Anthony  is important to you, please take a few minutes to do the following:

1. Contact Congressman Simpson (R-ID) and ask him to author a bill to release the Sand Mountain Wilderness Study Area (WSA) back to its' former use.
2. Contact your members of Congress and ask them to support a Wilderness Study Release bill so that WSA's are not left in limbo forever.
