Mountain Home Drill Hole is underway! Mobilization was completed on Saturday 9 July with rig up, and coring began early Sunday morning. First out of hole was massive variolitic basalt unlike anything seen on surface. Drilling continued to 201.2 meters with same basalt. Coring is being carried out with PQ size drill string (3.35 inch core - almost twice as heavy as HQ core). Because of its size and weight, core runs are only 1.5 meters long. Coring through upper basalt layer, into first sniff of sediments underneath. The Lake Science crew waits to punch through into lake sediments; logging basalt as we go. Site Chief Scientist Alexander Prokopenko (South Carolina) and Co-Chief Kristina Brady of LacCore presiding.
