At the equinox, Alan was away so I set the sunrise marker on the observatory on my own. From the west side of the field I sighted east through the aluminum pole in the center of the field, to the eastern horizon as the sun appeared. Then I pounded this stake in the ground with a large hammer. It came out pretty close to the autumnal equinox stake from last September, as it should. We'll keep adjusting these points as time goes on, until we figure out what to use for permanent monuments around the perimeter of this 11-acre field.
As I did in September, after setting the stake I hurried down to our entrance at the county road, to watch another sunrise from below the top of the bluff and demonstrate how precisely east-west is the road alignment. It was so cold! About 10℉ and -5℉ windchill, painful to face and fingers.
And a few days later, another snowfall. For hours and hours, in barely-freezing temperatures. Perhaps for the last time this season, the farm was transformed into a winter dreamland.
This is the back end of the shooting range, the 80-yard rifle targets. You can see the platform in the background. The "chimes" are 1/2" plate steel and stainless steel.
