Wine Country Geology - Grapes, Geysers, and the Petrified Forest, Napa County 7:00 am – 5:00 pm
Leaders: Jim Jacobs, CPG-07760 and Gary Pischke, MEM-3042
What can be better than a day of California geology? How about a day of geology and wine! This field trip takes you west of Calistoga, where we’ll see the California Petrified Forest - giant petrified trees preserved from the 3.4 million-year-old eruption of Mount St. Helena that hit the forest with a Mount St. Helens type blast. We’ll stop at the Calistoga Geyser Visitor Center (Calpine) and have lunch. The highlight will be a stop at the Sterling Winery and Aerial Tram in Calistoga, repre- sentative of a high-quality Napa winery. The aerial tram will take us to stunning views of the Napa Valley. On the ridge, we will discuss the rich volcanic soils, which are home to one of the great wine-growing regions in the world, followed by wine tasting at Sterling Vineyards. We will review terroir, as well as the recent fire damage, and have a stop in the historic town of St. Helena if time permits. Our return will be through the California coast ranges to Sacramento (the order of stops may vary). Certainly, a day well spent.
