About this map

Antelope Valley transitions sharply into the dramatic elevation of Portal Ridge in this 1930s survey of northern Los Angeles County. The map details a landscape defined by its geological faulting, most notably the San Andreas Rift Valley that cuts through the southern portion of the quadrangle. This tectonic feature creates a natural corridor for transport, followed by Elizabeth Lake Road and Pine Canyon Road.

Rural life in this era is anchored by small community landmarks like the Leona Sch and Belleview Sch. Agricultural and residential development is evident along a grid of surveyed avenues, including Del Sur Road, while the prominent Quartz Hill rises near the eastern edge. Water sources essential for the region's semi-arid environment are meticulously marked, such as the Amargosa Well and the seasonal flows of Amargosa Creek and Pine Creek.
