The Temperature Discrepancy
Temperatures had been roughly what the scientists had expected and had been stable inside the borehole for the first 10,000 or so feet. Surprisingly, however, past that depth, the temperature shot up to unexpected levels at a very quick rate. Inching closer to their target, the hole was suddenly a full 176 °F (80 °C) hotter than anticipated, meaning it had shot up to 356 °F (180°C) in no time at all. And there was more to it too…
