The post holes were drilled by a crew I hired that had a regular power line post hole digging truck. Their large 18 inch diameter auger made the job much quicker. the good part is that the holes got dug, some as deep as 4 feet. The bad news is that due to large underground rock croppings the drill auger drifted badly on the two eastern holes (the right side of the image). The earth literally moved about ten feet north and south of the bottom right hole as the auger locked up at 24 inches depth. The same underground rock forced the top right hole to the left 14 inches. The results were still workable dure to the design of my observatory support.

Saturday May 3rd 2003 with help from Robert Baker and Coy Scott, fellow CAAS members and friends, we managed to get three of the 5"x5"x12' posts leveled, set and concreted in. This image is from about 75 feet away. The posts extend ten foot above the white 18" diameter sonotube.
