Geo 365: July 19, Day 200: Drilling Rock

The rock drill on its inaugural borehole. Chris sampled five of these silty/muddy horizons, working down section, and successfully collected 19 cores. I didn't actually count the total number of holes, but many of the cores fell apart. I imagine the number of holes drilled was nearly double the number of cores actually collected.
In this crop of the above photo, you can see the muddy cooling water flowing out of the drill hole.
