USA, New Mexico: New Designation Would Further Protect Valles Caldera Geothermal Resources

It can be difficult to remember that the 89,000-acre Valles Caldera National Preserve actually encompasses a 1.25 million year-old dormant volcanic caldera.

The keyword is dormant – not extinct. The magma chamber beneath the surface produces a number of geothermal features both within and outside the preserve’s boundaries, including hot springs, warm springs, acid pools and fumaroles.

Because of the wealth of geothermal resources, the National Park Service has nominated the preserve to the Geothermal Steam Act list of “significant thermal features” within the national park system. If the Department of the Interior approves the nomination, Valles Caldera would be one of only 18 parks units within the 400-plus national park system with that designation.

According to Bob Parmenter, the preserve’s division chief for science and resource stewardship, the designation would serve two purposes: protection and an added level of distinction for the park.

The geothermal resources within the preserves boundaries have been protected from development since the early 2000s. This designation would add protection from negative influences outside the park’s boundaries.

According to Parmenter, protection under the Geothermal Steam Act “would established the fact that these geothermal resources are important to the national park service and the people of the United States, and the fact that if a development is proposed, it must be shown that it will have no negative effect on the geothermal resources within the preserve.”
