Laura said she'd like to be surprised for Mothers Day this year, so Zephyr and I hatched a plan to show her just how deep our love for her ran- by adventuring deep into the Earth at California Caverns near the Calaveras County town of San Andreas. The majority of the cave was still flooded from winter rains and elevated groundwater tables, which abbreviated our tour... but the good news is that water is what helps the caverns grow! It's pretty amazing to think that the carbonate minerals in these caves use to be tropical shoals several hundred million years ago. It's even more amazing to think about how subducting ocean crust scraped these deposits-off and accreted them to California. Awesome!
