Hi, Nathan–
Maybe the loose boulders are weathered enough that the andesite falls apart so
"accomodatingly", but I hope you were not talking about the solid rock of the
roadcut I was beating on. I would not want to meet anything less
accomodating… There were more weathered sections where I could knock off a
stone or two with every hammer blow, but the place where I found the seam of
calcite/aragonite and chalcedony/opal was quite refractory, and I spent a long
time on the ferrierite pocket as well. It would have been somewhat better with
a 3-pound hammer, but I remember almost as much work getting out some calcite
further down the Kanan Road on an earlier occasion with that larger hammer.
Why settle for a trinocular microscope? With four, you could take stereo
picture pairs while watching the specimen. Get a laptop PC with two high-res
video ports, a pair of displays that allow the screen to be projected by an
overhead, set up a visual baffle between the projection destinations… Why is
my Christmas list always so hard to lift?
