The National Park Service will mitigate safety risks to visitors by removing equipment and debris at an abandoned sulfur mine at the Valles Caldera National Preserve. The work will also support the restoration of natural conditions within the Preserve.

Why? One of the primary access roads to Valles Caldera National Preserve runs through the middle of the Sulfur Springs site where pristine views are interrupted by mining and non-historic debris. An open, acid-filled impoundment at the site poses public health and safety concerns. The continued erosion and alteration of the hydrology of Sulphur Springs impairs the natural landscape and can harm native plant and wildlife communities.

What else? A naturally functioning ecosystem is the basis for healthy plant, wildlife, and human communities. Restoring the natural function of Sulphur Springs will support native plant and wildlife communities. Once the area is restored, visitors will have the opportunity to experience the rare geothermal features of Sulphur Springs.
