Barstow

Junction:

California city, crossroads for early emigrant trails, railroads and highways in the California Desert, on the Mojave River. Once a small mining center and railroad town in California's Mojave Desert, Barstow is located at the junction of 3 major highways -- Interstate 15, Interstate 40 and State Highway 58. 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. Population is 21,500 and elevation is 2,106 feet above sea level.

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.

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.
