Cicadas Sing at 9:45

All is quiet, at least from the cicadas, at seven, and eight, and even nine. But at 9:45 they burst out with their incessant singing. I'm no expert, but it must be the temperature. They sing in the day, they sing in the night, so it can't be the light. Once the temperature gets up to about 80, they sing out, and don't stop until it cools off late at night. That's my theory and I'm sticking to it.

Mapped more of the area around the high point today. Lots of little bare rock areas and boulders. It should be interesting terrain for orienteering. I also found a hollowed out spot on the top of a rock that looks suspiciously human made. A grinding stone?

Lots of dead tress in this area, still standing. Why? I have no idea, unless it's the shallow soil above the granite outcropping.

I only do half days in this heat - more tomorrow.
