Summary: Final field notes - the site has been removed
| Sherman 2015-05-12 I arrived with Dennis, Cove, and Patty at about 9am. There was no active tractor work near our site so we just set to work, but soon the water truck driver told us we needed to check in at the office trailer. We checked in but they didn’t have enough hard hats and vests. Because there was no tractor work in our area, they gave us a pass on the safety stuff. It was a cool sunny day with a strong breeze from the west. Cove and Patty rolled up all the barbed wire and pulled all the fence posts with the help of the sheepherders jack. The wooden 4x4 posts were in good shape. The metal T-posts were ok but a little rusty. Dennis and I focused on getting the tower and box taken apart. I measured the locations of all the ground sensors. Theta probe #1 was at 15cm and almost completely rotted away. Theta probe #3 was at 23cm and was in good condition. Theta probe #2 was at 30cm and was in good condition. Soil Heat Flux plate #2 was buried in heavy Bermuda grass and the cable was completely rotten and broke during extraction. Over all things came apart relatively well despite some seized bolts. The tower was almost completely held in place by the guy wires and simply fell over when two guy wires were released. The box came apart easily being mostly glued together with black silicone. Power was still available at the site. After we used the power for some drilling, I turned it off again and removed the final power lines. The two original power lines were in conduit buried almost 2ft deep. By digging out and removing the ends, I was able to pull to power cords out completely – the conduit was left in place. I removed three of the four breakers. The remaining breaker will provide power to the GFI outlets in the small box. Everything was packed into the two trucks. We took the lumber, fencing and box parts to Twitchell and piled them up there at the base of the levee. Some metal was dropped off at the Gilman recycle center and everything else was brought back to the lab.
