Logged to 1173.6 feet, moving boxes around, drilled through the flank of a cinder cone!

Yesterday much of our day was spent moving core boxes from the rock lab to the armory, bringing new boxes to the lab to be logged, and bringing deeper boxes into the drying area.  As a result, we didn't get that much logging done until today.  We have now logged another 111.5 ft to a depth of 1173.6 ft, and we still haven't quite reached the base of that alternating pahoehoe/cinder sequence I mentioned in the last post.  Here's a representative image from our log reports of one of the box units within the sequence:

As you can see, this box unit contains the 31st and 32nd cinder fall deposits of the sequence.  At the depth shown in the photo, there are 32 mineralogically similar pahoehoe flows in the sequence as well.  I suspect we've drilled through the flank of a stratified cinder cone that may have almost constantly produced both lava flows and cinder fall deposits as it grew.  Thin, hot pahoehoe flows like the ones we've been logging are known to dominate the near-vent flanks of such cones.  From top to bottom, this sequence is ~190 ft thick and contains 40 cinder/pahoehoe intervals.  For comparison, the currently active Puʻu Oʻo cone on Kilauea's east rift zone had 44 eruptive episodes in only three years while building to its maximum summit height of 837 ft, and produced both lava flows and cinder fall deposits during this time.
