Juneau, J. 1992 Journal Big Bend River State Natural Area 20 miles E of Presidio, Presidio Co., Texas May 22-27 from an archeological viewpoint. In between talking to these visitors, I (set up) set the Las Cuevas nets up and running by 06:50, but the Ojito Abierto nets didn't get opened until 07:45. Except for one by my ford in the thorn brush, I served all the nets at midnight. The nets remained open until 17:00, Day after anything was being caught. After closing the nets I went on a wild goose chase, suggested by Aug. He described a group of cottonwoods at Cotton Tank, a site ENE of the falls atop Ojito Abierto. The place is accessible only by a long walk from a trailhead about 4 miles beyond the turn off to Ojito Abierto; the croke itself is about that long, too. I found the Cotton Tank. It had no water, it had no cottonwoods (a few mesquites only), and it had no greffridges. It did have a Big Bend Patch- nosed Snake & a Copperhead's Fourmore. It also had a scenic view of high mountains in the distance in Mexico (Sierra del Kido?). Weather May 25: unlike cyclic breezes early, but mostly still until 15:00. A light low rapidly evaporated. After 16:00 steady w winds 5-20 kph increasing toward sunset. Only few clouds 12:30 to 21:30. Big T- Clouds to W & N, but for the first time since I arrived, none one seen today in the E. Temperature 65° - 70° - 70° F. On May 26, I ran nets at Las Cuevas & Ojito Abierto from 06:20 to 14:45, when threatening weather & winds prompted me to close them at Ojito Abierto first, then time at Las Cuevas. I saw up yesterday's mess and corralities in mid afternoon, and am feeling very well, I passed late afternoon & early evening. I briefly was huntal after sunset (21:15 to 22:15) but saw only unidentified small rodents. Weather May 26 dawned to a solid low sourced, clearing until 09:15, then slowly clearing until totally clear at 09:30. The low clouds disappeared and when they froth up at 14:00, revealed were thunderclouds
