It is centrally located in the western Mojave at the entrance to the Mojave National Preserve and is home of the U.S. Army National Training Center, Marine Corps Logistics Base, NASA's Goldstone Deep Space Network and Burlington Northern-Santa Fe Railroad Yards.

Literature Cited: - Harter, Russell G., 1972. - Ramos, F. C., and M. R. Reid, 2005. Locations: Pisgah Crater.	Pisgah Crater is a recreation site, with several lava tubes that can be explored. The composition of basalt in the lava flows has also been the subject of controversy regarding the source of the magma reflecting sequential melting of ultramafic to mafic mantle sources. Some papers support that hypothesis, while others suggest contamination by crustal sources.
Locations: Pisgah.
Literature Cited: - Adams, James D., and Dana A. York, 2005. - Sanders, Andrew C., n.d.. Locations: Lavic.	Lavic south of the highway. Psorothamnus fremontii (A. Gray) Barneby, Fremont's Indigo Bush, from near Lavic was studied by Adams and York (2005). This is also a location where Castela emoryi (Gray) Moran and Felger (Crucifixion Thorn) is found.

There is a collection of Frasera speciosa (George E. Osterhout 6997, 6/23/1928, RM 25887) described as "between Grand Canyon and Maine." Typically this is mapped at Tusayan. I think it more likely the collection was made closer to Maine, or perhaps near Sitgreaves Mountain, which is between Grand Canyon and Maine.
