Did you know there are volcanoes just a few miles from downtown Clayton? Disguised by a canopy of dense oak woodland, a number of volcanic domes are hidden in plain sight … if you join us to see where to look.
Save Mount Diablo (SMD) recently acquired a 7-acre property on Marsh Creek Road which turned out to be composed of rhyodacite, a type of volcanic rock formed when rising magma cools in two stages. Further investigation showed that a series of these volcanic rock formations are found in the Marsh Creek – Morgan Territory area.
SMD’s dome is steep, rugged and covered in poison oak, but we’ll be leading a hike around a similar, more easily accessible, volcanic dome in Perkins Canyon, Mount Diablo State Park. Rare plants, great views and fascinating geology make this a great two-mile, 350′ elevation gain hike, not to mention an amazing creek, historic rock dams and lots of history.
