Santa Cruz Main Beach, El Nino

Photographs are of the Santa Cruz Main Beach before and after the December 11, 2014, “Super Soaker” storm that brought 2.5 inches of rain in just a few hours to Santa Cruz and 9 inches to Boulder Creek, along with big waves and swell. While the human eye may notice changes to the beach, ground-based lidar can create surface maps of precise elevation changes over time.
