and please let them know if you are coming.
Bruce Rogers will give us a scientist and explorer’s insight into selected caves of the Greater San Francisco Bay Region. The region is not noted for its abundance of known stygian sites, but they aren’t absent. Some you can visit and some you’ll likely never see for yourself, given the restricted access. We’ll include a quick look into the multitude of sea caves (some of national importance); tafoni shelters (a few with fascinating cultural and natural history); unusual caves comparable to only a few other locations world-wide; and even a scattering of small limestone caves and their unique inhabitants. Discussion will also touch on cultural and architectural sites resembling natural caves.
Elephant Bay Entrance, El Reyes Cave
Bruce Rogers began cave exploring in the wilds of New England in 1958. Since then he has explored the basements of North America from the Atlantic to the Pacific and from Alaska to the Guatemala border in addition to many of the island nations of the Pacific Basin. All facets of geology and geography, cartography, photography, and history are included in his spelean interests. Author and/or editor of several books and scores of articles on caves, his current interests are lava tubes, littoral caves, cave history, and Pleistocene fossils in California caves. His interest in speleology led to formal geologic education and to a position as a field geologist at the USGS. There, he also indulged both artistic and scientific bents as a scientific illustrator and web person at the USGS for a third of a century. Since 2007, he has been writing prolifically and is President of the Western Cave Conservancy.
