Tues March 01, 2011 at 19:46. We are at a depth of 617.9 meters. Core has varied from nasty mudstone and clays that have bound up the bit. We have cored quite a bit of what we called ash that has been altered. Our last run had a section of rhyolite that ranged in colors from red to to green. The wire line on the rig is messed up and made a big rat's nest.
