Santa Catalina is the inverse Atlantis of California's Channel Islands. From crushing, tectonic power within a shifting deep, it emerged as a perplexing anomaly of geology and maintains a youthful topography. The island is in good company with California's diverse geomorphic provinces. Our field day challenged us to look closely at what might otherwise be taken for granite.
To lead us through layers of time, heat, and pressure was John Turbeville. His deep knowledge and personal connection to Catalina provided nimble and thoughtful interpretation, encouraging us to ponder and question the very ground under our feet. We uttered odd words like schist, quartz diorite, andesite, serpentine, rhiolite, amphibolite. We magnified weathered surfaces of ancient seafloor with our hand lenses to marvel at the alchemy stirred up by our planet's athenosphere.
