San Francisco Bay Area Geology Resources

Below are Geology & other Earth Sciences resources I have discovered & compiled over years. Unfortunately I have lost track of the original locations of almost all of these sources. So, for academic purposes, you should cite the source itself, not this Appreciating Earth website.

  • Download at: or Apple Store or Google Play

  • I share how to use the Rockd App to discover & learn about local geology 

  • The intricacies of rock identification & map skills

  • Why should we care about the rocks beneath our feet, in terms of environment, climate, natural hazards & agriculture

  • Note the video on the right does not have sound
