View to the north with Tien Shan in background. Strange bird in bamboo tree. Actually, this is Xu Yi, trying to inspect our work on the roof of the observatory. Hired help from Wuqia village digging a hole for the sensor in the northeast corner of the observatory compound. Guralp CMG-3ESP placed on a cemented tile at the bottom of the hole.
Depth is slightly more than a meter.
No bedrock here, just a lot of cobbles. Filling in the hole. Setting up the DAS in the observtory with the Palmtop. Wires go though hole in bottom of window frame to sensor, solar panels, and GPS clock. Guo Biao doing the honors.
