BALT-CZU Landslide Monitoring Site

Detailed Description

The USGS “BALT-CZU” site is located in Santa Cruz County, south of the San Francisco Peninsula, near the town of Brookdale.  The site consists of instrumentation monitoring the hillslope in the central part of the image. This slope is typical of many in the Santa Cruz County region that exhibited moderate to high soil burn severity from the CZU Lightning Complex wildfire. Nearby slopes have generated debris flows in the past. The area consists of a fully burned land surface with only tree trunks remaining. The soil profile consists of a 2.5 cm layer of ashy charred leaf litter and a 0.5 m horizon of gravelly sand underlain by highly weathered diorite bedrock.
