Rio Vista Field Trip

David Vail will be leading a field trip this Saturday, April 8th, to Ham Creek near Rio Vista (about 80 miles S of DFW, S of Cleburne on TX 174).  Participants should meet at the Meat & Potatoes restaurant (100 TX-174, Rio Vista, TX 76093) at 10 am.  The group will have coffee and/or breakfast there and then leave at about 11:30 am.  This trip is a wading trip, so very young children or those unsure of their footing are not recommended.  The creek is mostly shallow, but has some sections that are knee-deep, so participants should wear shoes that can get soaked, such as old tennis shoes.  It is highly recommended to put cell phones, wallets, and car keys in zip lock bags, inside a larger zip log bag, or in a waterproof dry bag, and leave a towel and dry socks and shoes in the car for afterward.  David reports that fossils to be found are mostly ammonites, with some echinoids, corals, and other invertebrates, from the Lower Cretaceous (Duck Creek, Kiamichi, Edwards, and Comanche Peak).  You do not need to sign up in advance, just show up, but you can contact David on his cell phone at 214-738-8643 if you have additional questions or can't find the restaurant.
