From the text ... 'To demonstrate what can be accomplished through modern management when the lands are concentrated enough to be manageable, BLM last year began a Resource Conservation Area Program. The so-called :RCA's' were established on some 85 public land bundles, ranging from a few hundred to a few thousand acres in the 10 Western States. Signs, interpretive leaflets and colorful names such as Calamity Ridge in Colorado, Paradise Valley in Nevada and Spanish Spring in California, all helped identify for visitors these areas which will serve as testing grounds for management techniques. Among the soaring values of public lands is their recreation potential. Acres of desert in riotous bloom, cool wooded camping spots, antelope poised at a stream's edge, clear air and brilliant sunsets-these are features that make our public domain, with its semiarid flavor, a perfect outdoor complement to our lush National Parks and Forests. As part of the Nationwide Outdoor Recreation Plan, BLM is conducting an inventory of the recreation possibilities on its 464 million acres. Scheduled for 1966 completion, the search is literally 'unearthing' thousands of individual areas of major significance for hunting, fishing, water sports, winter sports, rock collecting, camping, picnicking and hiking.
