Little Magadi Soda Lake. Fed by a hot spring-fed river at the far north end of the lake.

On the 17th the broken subdaptor was taken to the mine machine shop for repair, but because of meetings related to the imminent mine layoffs the repair had to ultimately be done on site. Once the piece was repaired at the end of the day we were able to resume drilling about 5PM. During the downtime the day shift science crew went to visit Little Magadi soda lake about 20 km northwest of the drill site, so that Emma McNulty could collect some nahcolite samples and do some ongoing water chemistry measurements. See pics of our exciting day, which also involved some zebra and grants gazelle sightings and spectacular rift structure scenery. Once drilling resumed we started advancing slowly. Recovery of the interbedded cherts and green mudstones was very poor at first with bits of chert blocking up the liner and loss of mud almost entirely. But as the shift progressed and with a bit of experimentation the drillers got better at collecting samples of this complicated lithology and by the night shift (17th/18th) they were getting up to 50% recovery. The day shift is now back on for the 18th and thankfully so far it is cloudy which makes working here alot more pleasant!
