Here is another geologically-oriented book for you to bid on:
"Cavern Development in the Helderberg Plateu, East-central New York" by Ernst H. Kastning. This is Bulletin 1 of the New York Cave Survey. It is in like-new condition, except for where I wrote my name and NSS number inside the cover. The book is Softbound, 194 pages long, with additional un-numbered pages at the end that are very nice maps and a large, folded, loose map of McFails Cave. This book was Ernst H. Kastning's Master's Thesis at Rensselaer Polytechnic Institute in 1975.
All kinds of good stuff: black and white photos, graphs, tables, etc. Definitely a "Classic" in the karst literature.
This item is easily as rare as the last item, so I am going to start this auction at $20, also. All bids above $20 must be in even-dollar amounts. Postage is $3.00 extra. No International Shipments.
This auction starts tonight, Wednesday, September 12 and ends next Wednesday night, September 19 at 8:00 pm.
