Houston Gem & Mineral Society Field Trips

The Houston Gem and Mineral Society goes on as many field trips as possible. We have cooperative field trips with the Clear Lake Gem and Mineral Society and anyone else who wants to organize one. Some of us are also members of the Southwest Gem & Mineral Society of San Antonio, so we can go on trips with them. The primary focus of most of our trips is for paleontology items because fossils are much more prevalent in the eastern half of Texas than anything else, but there are sometimes trips out to the Texas hill country for topaz, Llanite, and other minerals, and out to West Texas for agate as well. Some of our fossil sites are as close as the Brazos River or Waco, and some have been as far away as the phosphate pits in North Carolina.

Field trips are announced on the club email blast. You must be a member of HGMS to be put on that email list.

========================================================================================

Mike Dawkins is the field trip leader for the club and for the Paleo Section. The field trip email addresses are field_trips@hgms.org and hgms.trips1@gmail.com as emails are occasionally rejected by the HGMS server.

All people going on HGMS-sponsored trips must be a paid-up member of HGMS, and they must sign an Assumption_of_Risk form each calendar year. (If the form initially appears quite small, click on it to enlarge.)

The club does not charge for field trips, but sometimes the sites we visit charge an entrance fee.

Join the club, and join us for a field trip.

If you have an idea for a field trip, email Mike Dawkins at field_trips@hgms.org! So much land is private in Texas that it is hard to find places to go. We can provide a liability release for land owners and may be able to negotiate a fee for access or a price per pound for collected material.
