Clay mystery disks

geeze... I go looking for these things and come up with nothing... this guy just goes diving and finds 20 of 'em.... Had a couple really nice dives though and probably my best SAC rate ever...

I'm still convinced you secretly bumped your tanks up to 4000 psi before that dive....

What do you mean tankS (as in more than one)?

I figure you switched up when I wasn't looking......

I wish I had written down my tank pressure so I could figure out my SAC rate for both dives. 118' max with total dive time of 36min and another to roughly 40' max with a total dive time of 63min all on one 98cf LP steel Faber filled to the rated capacity.

Anyway, sorry for the thread hijack... back to the clay discs.

You mean to tell me these are NOT ancient Indian artifiacts I have been selling on Ebay?!?!?!?!? :11:

They are definitely concretions. I sent those pics to Prof. Ed Klekowski at UMass. He is the guy that made the "Under Quabbin" film and, more recently, a documentary on the early CT River log drives. He also teaches an on-line course called "Under the Connecticut". Anyway, he positively I.D.'d these as concretions from varves formed by Lake Hithcock at the tale end of the ice age. He says they are between 12-15 thousand years old. I came across hundreds of them but please don't ask for a specific location as I'd just as soon have them stay there for another 12K years. Dive the river often enough and you'll come across them.
Scubasaurus was the first one in with the correct answer. I don't know what you win for that but you should of heard some of the answers I got when I showed them around. I thought petrified dinosaur dung was a good one.
