I continued past the pair of glacial erratics, and after following a 135 degree azimuth, I discover yet another pair of glacial erratic stones. Again I am not certain of the significance of 135 degrees. I took an azimuth reading at the exact middle of the boulder pair, there could be a difference plus or minus 5 degrees. The only thing of significance that I found for this alignment was centered on the azimuth of 130 degrees:

As winter began the rising sun would move closer and higher away from the left stone; as winter receded, it would initially rise to the left and closer to the horizon.

As for lunar significance, I obtain the following data:

The pattern that emerges is the mid cycle moon will initially appear going lower and lower in horizontal altitude toward the boulder pair, which I estimate has a degree span of 130-140 degrees. It gets to it lowest point at July, or mid summer, then rises up again. In December the mid cycle moon does not have a horizontal appearance within the degree span of the boulder cluster. This is when the sun is used with this would cluster to determine the progress of winter. Brian Ghilliotti
