The Grizzly Peak Research Natural Area rarely gets visitors, but the area is getting some added protection to keep it from being disturbed.
Researchers say it provides a baseline for what a natural area should look like.
The research area is located along the summits of the Rico Mountains and the headwaters of the Dolores River.
The Cortez Journal reports snowmobilers will no longer be allowed to access the area and backcountry organizations have been notified about the closures.
