There will be a scheduled project trip to Amistad National Recreation Area near Del Rio, Texas on the weekend of September 11-12, 2010. I have slots for about 15-20 people so this will be a first come-first serve opportunity for folks. The goals for the trip will be to: 1.) Relocate caves and karst features that were noted by the International Boundary Water Commission back in the early 1960s. We have rough locations and descriptions but no one has relocated and surveyed these features since then. 2.) Explore and survey the caves and karst features that have been relocated. 3.) Ridgewalk areas that have no known caves. Camping will be provided by the NPS at the group camping site. For those that want a warm bed and sit-down meal, Del Rio is only about 15 minutes away. Some of the caves may be vertical and/or require digging to open. The flora in the area can only be described as vicious so bring tweezers and long pants. Heavy hiking boots are a must if you don't want the cactus and lechuguilla to cripple you. The weather at that time of the year will be warm and probably dry, so plan accordingly. If you have any questions, please contact me off digest. I hope to see you all out there. There's plenty of caves and karst for everyone ! Jerry Atkinson.
