Twitchell Rice
2013-11-06

We arrived about 11:45 PST. It was sunny with high hazy clouds, warm, and calm with a very slight breeze from the east. The field is fully flooded, water table about 20 cm above the surface. We built a boardwalk out to the tower. The Met box was full of wasps, which are entering through the dislodged silicone filling the holes in the bottom. We need to seal these holes again next time.
