the transfer of renewable energy. It explicitly does not create any protective perimeter or buffer zone around the monument and does not grant the government any additional authority over non-federal land within the monument. Approximately $45 million of private donations and $18 million in federal Land and Water Conservation funds were spent to purchase land from the Catellus Corporation between 1999 and 2004 with the promise of conserving it in perpetuity. However, the BLM subsequently accepted applications to build solar and wind energy projects on these former railroad lands. The California Desert Protection Act of 2010 provides additional protection for approximately of these acquisitions, prohibiting disposal of this land or additional mining, rights-of-way, leases, livestock grazing, infrastructure development, or off-highway vehicle use. The proposed Sand to Snow National Monument covers of federal land between Joshua Tree National Park and the San Bernardino National Forest in San Bernardino and Riverside counties. The bill maintains existing recreational uses, including hunting, vehicular travel on existing open roads and trails, camping, horseback riding, and rock collecting. This monument would be jointly managed by the BLM and the U.S. Forest Service. Land additions to existing national parks The California Desert Protection Act of 2010 adds approximately of land to the National Park System. The additions to Death Valley National Park total approximately . The largest parcel (31,000 acres/48 sq mi/130 km2) is known as the "Bowling Alley"—a narrow strip of land between the southern boundary of the park and Ft. Irwin that was designated a wilderness study area by the California Desert Protection Act of 1994. The "Crater Mine Area" (6,400 acres/10 sq mi/26 km2) is a former sulfur mining area in northern Death Valley that is entirely surrounded by Park wilderness. The bill adds a area containing the Castle Mountains on the border of Nevada to the Mojave National Preserve. This land was left out of the original California Desert Protection Act that created the preserve due to an open-pit gold mine that was still active in 1994. The mine has since been closed and the mining company has largely restored the land. The bill adds approximately to Joshua Tree National Park in the form of multiple small parcels of BLM land on the northern boundary of the park that have been identified for disposal. Wilderness and wild and scenic rivers The bill designates approximately of wilderness in five BLM Wilderness Study Areas near
