EndX Fence Anemometers Put Back Up

Managed to get through the tumble weeds to layout the wind sensors.  Attached is 6 hours showing the direction sensor and the two speeds starting back up a few hours ago.  Speed_4 is on top of the building near the PEM sensor and has continued to run while all the others were off line.  I'll put in a comment with an updated location map but I'll say now that all the senors are 39' +Y of the Wind Fence line.  Maybe not exactly free-stream but that was all the cable we have.  I hope we can extend this to get further +Y and higher altitude.  The direction sensor and speed2 are 17' above ground level (AGL) and speed3 is 12' AGL.  They are about 21 to 29 feet -X of the Wind Fence X position center.

Here is a sketch of the wind fence anemometer locations wrt the fence and the EndX building.

Also there are a couple photos of the cable route up the slope through the tumbleweeds (they are over head height) and of the sensors with the fence.
