Almost all of our proposed 13,400-acre wilderness is a designated BLM Natural Area that is closed to motor vehicles. Our proposal also includes the natural part of the sand dunes south of this area. These dunes are seldom used by ORVs and are a logical part of the wilderness. There is only a single, one-mile-long vehicle way intruding into the proposed Rockwell wilderness, and it was declared by the BLM to be "substantially unnoticeable." Thus, the entire area is in a natural condition.
The proposed wilderness is bordered by the 60,000-acre Little Sahara Recreation Area, two-thirds of which is available for ORV use and would remain open even if the Rockwell area were designated wilderness. The BLM has not proposed wilderness protection for any of the Rockwell area, yet is applying restrictions on ORVs within its natural area that are similar to those for wilderness areas.
