Wireline drum broke on Tuesday so not much drilling completed -- drum repaired but new drum is being shipped up from SLC. Core continues to be very dense from low temperature alteration. Vesicles and pockets are filled with celadonite (blue-green clay/mica), which also heals fractures and apparently replaces former interstitial glass, giving core a bluish tinge. As a result core retrieved in long chunks -- see photo for 2.4 m piece that came up with temperature probe. We are now at 1127.8 m. BHT at 1120.4 m is 34.2 C -- putting us on a gradient of ~155C/km below the aquifer. At this gradient we should hit 100C around our planned depth of 1.5 km. Weather conditions -- cold and cloudy, but not as windy as Monday-Tuesday, when they had to stake tent down with extra guy lines. More weather on its way.
