I arrived about 11am with Dennis and Siyan. It was mostly sunny and cool. There was a lot of frost and frozen puddles along the road in the valley. The ground is very wet. The pond is close to full, but not as full as I have seen it before. Where the Cosumnes crosses Twin Cities Road the water level is about as high as I have ever seen it. The grass growth has stalled due to cold temperatures.

I collected data and serviced the z-cams, Dennis did the soil moisture and Siyan did the wells, dbh and clip plots. The co2 profile system is still off.

Both z-cam 2 and 3 need their windows resealed. They are both held on with putty right now.

The pyranometer at the tower top needs new desiccant.

We took apart the tram. We spooled up all the fence wire, pulled the posts and disassembled the track. Part of the track is bent where it banged against a tree. We left all the parts on site but brought in the solar panels and most of the hardware that was removed.
