When surveying a cave we always use Rite-In-The-Rain paper. It is almost completely waterproof. I have managed to dunk my survey book in a stream for minutes at a time. The paper and the pencil sketching survived. It also survives getting muddy. They offer products that will go through a laser or ink-jet printer. http://www.riteintherain.com/ For long-term storage (decades or more) the jury is out. I have survey notes from 15 years ago that are still usable. They are stored in an ordinary filing cabinet in my house - No special environmental efforts are taken. It seems reasonable that Rite-In-The-Rain paper will store at least as well as regular paper. It is pricey, but if you really need waterproof then this is good stuff. Bill Gee
