Ropy pahoehoe

As promised, here's a representative picture of some of the pahoehoe we've been seeing.  The black rock has been cut by the drill bit, the brown rock is an exposure of the "ropy" surface of a pahoehoe flow.  In this case, it appears that there was a void space that was not completely filled when pahoehoe lobes were emplaced next to and on top of each other.  Later flows buried this void space, and that way the ropy surface texture was protected and preserved all this time.  We have seen lots of this kind of ropy pahoehoe lava flow morphology over the past couple days.

We boxed rock to a depth of 534.8 ft today, and logged the previously boxed rock to a depth of 296 ft.
