By George Dasher
There is an international standard regarding survey datums, cave length, cave depth, and pit depth, which this talk will describe.
George Dasher began caving, cave surveying, and project caving in 1975 in the 38.5-mile-long Organ Cave System in Greenbrier County, West Virginia. His first three trips were not “fun,” but he stuck with it and has since focused on documenting West Virginia caves and karst. To date, he has ridgewalked and surveyed caves in all of West Virginia’s karst counties, as well as completed a significant number of successful dye traces. He is also a prolific writer and editor of cave-related materials, and has edited The West Virginia Caver since its founding in 1983. He has also produced several publications for the NSS, including both editions of On Station, the NSS’ publication on cave surveying, and nine West Virginia Speleological Survey bulletins. He is currently the Executive Director of the West Virginia Speleological Survey, the secretary of the Surveying and Cartography Section of the NSS, and the vice-president of the Charleston Grotto.
