Probably pahoehoe

The drilling slowed down a bit last night due to encountering some unconsolidated material, but that issue appears to be resolved now.  As a result, the core processing crew got to do some logging this morning.  The picture below shows all the boxes we have in our lab that have been photographed and are ready to be logged into the database. 

The logging for these boxes should actually go pretty quickly, if we can find the time to get to it.  Most of our time so far has been spent trying to get the core boxed fast enough to keep up with the drilling.  We processed rock to a depth of 491 ft today, and saw what appeared to be our first pahoehoe unit(s).  This could be a significant find, because post-shield stage flows generally don't produce this lava type.  The pahoehoe flows also contain no xenoliths, another indicator that they are from Mauna Kea's shield stage rather than it's alkalic cap.
