Hey Jim...I'm looking forward to it! I used to have some large chert nodules, but in all the moves I've done...dumped it. That's the problem being a geologist, you end up hauling a ton or 2 of rocks around with you for the rest of your life and sooner or later, you just gotta lighten the load!
Have you gone out near Delta and dug in the welded ash flow tuff for the Topaz or the red Beryl? Hard digging, but there's some pretty impressive stuff to find. I'm thinking...there's some trilobites to be found out there as well. Doug
