What I'd like to find is references to any articles that William wrote or talks he gave at TSA ec It'd also be nice to find what caves are in the area he was talking about. Sam S Sweet remembers William mentioning the El Max but they didnt find any salamander caves there so its not in his notes ( Sam was a grad student from Berkley who worked on Eurycea salamanders in the 70s and made really good field notes that present day salamander workers find very useful) The El Max was 7200 acres so 12 square miles or 3 x 4 mile sized ranch

The stratigraphy of the area needs a closer look. To the east at Honey Creek we see a well-defined and distinctive 9-m thick biostrome (a fossil reef bed) in which Honey Creek Cave is formed. That biostrome unit isn't exposed in the El Max/CWAN area. Those caves are stratigraphically higher in a part of the lower member of the Glen Rose that clearly forms abundant caves there, but relatively few and smaller caves to the east. Maybe this is simply a bias created by the properties cavers had had permission to explore, or maybe there is something going on geologically creating a true difference in cave development. The USGS has conducted detailed geologic mapping north of Bexar County. They recently completed some nice work in Comal County. I don't recall if they told me they would be mapping in Kendall County, which would help answer these questions, or if they just hoped for funding to map that county. Geary might know.

Does anyone remember anything about the El Max limestone ? Way back in the 60s cavers went to caves there. Bill Russell gave a talk, maybe wrote some articles in the Texas Caver at the time about the geology of that area. He suggested using the name El Max limestone for a very cavernous section of the lower Glen Rose limestone that was prominently exposed on the El Max ranch. These would be caves near the Guadalupe river ( I think) same sort of geologic setting as Cave-with out a name, Spring Creek, Alzafar water cave. I remember talking to William about this back in the 70s when we were looking for cave salamanders and Kendall county was one of our favorite places to go. I also sort of remember seeing something in a old TC or TSA convention notes. Looking up the El Max ranch it was 7200 acres and had Guadalupe river frontage. Part of it is now the Cordierra Ranch subdivision. _______________________________________________ Texascavers mailing list | http://texascavers.com Texascavers@texascavers.com | Archives: http://www.mail-archive.com/texascavers@texascavers.com/ http://lists.texascavers.com/listinfo/texascavers
