Underwater Cave Survey Class 1-2NOV14- A few have asked me to give an underwater cave survey class while I am down here in cave country. This is an opportunity for you to learn the basics of Walls cave survey software, and how to use it for cave diving, as well as two of the hardest cave diving skill days you will probably ever do (say some of my earlier students.) We will dive at Jackson Blue (no further than the shallow areas) and you will make your own basic map in two very long days. (Should be three days.) Skills include data entry, line plot creation, sketching, and discussion about laying exploration line with thought to survey. There is no cost to attend, though you must RSVP, as I can only handle 12 in once class. You must provide your own laptop with Walls software installed.
