Short hike before "Pegmatites!"­: SF Gem & Mineral Society's October talk.

A short sunset hike before the talk (sunset is 6:48). We'll leave at 5:30 PH (sharp), walk down Judah to Ocean Beach, head northward towards Cliff House. After about 30 minutes we'll turn around, and then return to the SFGMS to get good seats for the talk (and time to hit one of the few restaurants/cafes in the neighborhood where you can get take-out food as well).

If you can't make the hike, you're still invited to the talk :-)

"Pegmatites!" San Francisco Gem & Mineral Society's October general meeting

Speaker:  Christopher Lewis, Professor of Physical Geology & Science, City College of San Francisco

Friday, October 4, 2013  •  7 p.m.  •  Free 

Curious about Pegmatites? Professor Lewis will tell us all about them. Geological oddities, pegmatite are bodies of very coarse-grained intrusive igneous rock, usually near igneous bodies, with quartz, feldspar and mica as typical components. Some pegmatites contain just those minerals, in large crystal sizes; other pegmatites produce valuable "rare earth" minerals and radioactive species. But the famous gem-bearing 'pegs' are much sought after for their hollow pockets yielding colorful gemstones like tourmaline, topaz, aquamarine & other beryls, garnets and amazonite. These have put San Diego County, Maine, Russia's Ural Mountains, Madagascar – and most recently the Hindu Kush of Afghanistan & Pakistan – "on the map" for the world's mineral and gem dealers and collectors. Join us for a most enlightening evening!

Address: 4134 Judah Street, San Francisco (between 46th and 47th Aves. (2 blocks south of Golden Gate Park, not far from the Ocean Beach)

Phone: [masked]

Refreshments are served after the meeting. The N-Judah MUNI streetcar stops very close to our door Parking can be scarce; carpool & try on Judah St., or one block south on Kirkham Street. 

PS. No dollar requested for this "hike." I'm guessing the SFGMS will pass a bucket if you have any extra cash :-)

    The talk at the SF Gem and Mineral Club was excellent. The presenter teaches at SF City College during the day. Wish I could take her class.

    After that walk on the sand with that incredible sunset and balmy air, the lively talk on pegmatite was almost outdone by hearing the history of SF Gem & Mineral Society as told to me by a couple of members. Was fascinated by that little clubhouse and all they do there!

    Hi Lee,
    I apologize and am so bummed I couldn't make it! My daughter had twins (one month early) - so I'm 4 hours away assisting with the new family :>)

    I had forgotten how nice it is to walk on the beach. The weather was lovely and we took the time to watch a long sunset with the Farrallones also visible behind a low fogbank. Lee doesn't talk a lot but he knows the answers if you ask him.

    I won't be able to make it Friday, but look forward to other events.

    Low tide is at 5:47, so we should have plenty of beach to stroll on.

    October 3, 2013

  • Lee T.

    Looks like at least 12 of the RSVP folks are coming on the hike as well as the talk (some didn't answer the question, so I suspect there will be some more on the hike).

    Oh my goodness, this is the same weekend as Hardly Strictly Bluegrass in Golden Gate Park. I hope my favorite artists aren't playing Friday afternoon :-)

    Also, be aware that traffic may be heavy; if you're coming from the north avoid coming through Golden Gate Park, instead head towards Cliff House and Ocean Beach.
