Caspar, CA Coastal Erosion Rate
Is the coast eroding 2.6 miles north of Caspar, CA?
This segment, 2.6 miles north of Caspar, CA, falls in a gap in USGS's own transect coverage - no usable reading, so none is claimed.
What this reading actually covers
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Caspar, CA, rather than showing one arbitrary line. Segment center: 39.40, -123.81. The survey behind it runs to 1852-2016, in USGS's California assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
