I just got the latest order of Durawrite survey paper to the house, and it is ready to distribute. For those not familiar, the material is sold by the write in the rain folks as Durawrite- it is actually a plastic sheeting that you can write on with ball point pen (when dry) or pencil in any conditions, (we use it underwater.) It doesn't fall apart like write in the rain paper, and can remain submerged indefinitely, without losing your data. (until algae grows on it.) There are two versions- the cave diver version (which has a depth box in the place of a normal split elevation box, aligned with the station) and a dry caver version- standard cave survey format. Printed in blue ink, so you can discriminate between the boxes and drawing in reproductions, and the backside has the standard gridded paper (non-metric.)
Prices have gone up a couple of dollars- 27.50 per pack of 100 sheets, plus shipping ($5 west of the Mississippi, $8 east) and you can paypal me with your address at j@rchrds.org
The price is steep, but for those who have used it, there is no substitute. You can also buy directly from Rite in the Rain, but it is special order, and costs about $10 more a pack. (I have to buy $1500 bucks worth to keep the price down.)
