After two and half hours spent trying to retrieve a core, unforseen problems stymied our attempt and at 7pm this evening the core barrel was pulled out of the hole and contained only a few rock fragments. Nonetheless, scientists are excited about analyzing the gas content and mineralogy of these rocks from the crust adjacent to the fault zone. We are now proceeding to ream and condition the hole in preparation for the LWD as we continue our journey to the San Andreas Fault.
