Logged to 1609 feet, elongate olivine

After our first weekend off since the start of the project, we were refreshed and ready to log more rocks this morning.  After moving some core boxes into the different work areas, we logged 60.4 ft today to a depth of 1609 ft.  One of the interesting things we saw while logging today was the presence of elongate olivine crystals:

We have seen elongate olivine before, but today I saw one that was 5 mm long and barely the width of a hair.  These crystals are known to form during rapid cooling and/or crystal growth, and that fits with where we've been seeing them: At the margins of olivine-rich pahoehoe flow lobes where cooling can be rapid enough to form volcanic glass.
