Caspar, CA Coastal Erosion Rate
Shoreline change 1.5 miles south of Caspar, CA
USGS did not publish a reliable transect reading for this exact stretch, 1.5 miles south of Caspar, CA, so no rate is shown here rather than a guessed one.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Caspar, CA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 39.34°N, 123.81°W. Survey years: 1852-2016, method LRR, from USGS's California shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
