A volunteer effort by a group of coastal scientists and engineers asks residents to contribute their images and stories about California’s evolving coast for the purpose of a greater collective understanding. An interactive story map inspired by Orville Tyler Magoon, an engineer who playfully reinforced Humboldt Bay’s crumbling jetties with concrete forms designed to look like children’s jacks, features photos, videos and narrated slide shows from past and present. Contributions from the public will build upon over 4,000 slides taken by Dr. Magoon between 1960 and 2001, which were acquired by the California Shore and Beach Preservation Association in 2018. “The beauty of what Orville did was to focus on how structures, beaches and the coastline itself were, in a way, alive,” oceanographer Doug George said. Technological advances can inform coastal managers but offer little historic data and lack personal connections. On the other hand, historic photos can provide engineers, ecologists and the public with a visual baseline, Mr. George said. How has the coast changed? What is my personall connection to it? What does it look like before coastal engineering? Images and stories that answer these questions can be submitted by visiting www.asbpa.org/california and clicking on “Resources.”
