April 10, 2024 Meeting

A great showing for both the junior rockhounds program and the general program! In junior rockhounds, the kids learned about the three types of rocks: sedimentary, igneous, and metamorphic. Then they learned about mineral identification: the Mohs scale, a scratch test on tile, and an acid test (which didn’t fizz as much as we hoped so we’ll try again next time!). They are on their way to earning their badges!

The general program, a special presentation by Scott Johnson, Geology Faculty Member from Cal Poly – about “Local Geological Formations” was very informative. These included the Franciscan Complex melange made of many types of rocks. The volcanic Morros are younger and popped up through the Franciscan Complex.
