Is the 41,000 year cycle related to the ca. 40,000 year solar cycle that influences ice age dynamics? I am sorry that when at Maes Howe 28 years ago I did not experience an alignment event though there on the summer solstice. I cannot remember what I was told about the entryway's event alignment. I would love to return there with all the recent discoveries that have occurred. I was lured there initially by family origins on Westray. Now I read that the small carved stone balls from Skara Brae are dead ringers for pottery balls found at Watson's Break complex in Louisiana. That would be an interesting connection to understand! Maybe Farley Mowat was hot on the trail with his 'Far Farfarers' if I remember that book title correctly.
Springhead ,
I think I have a much better grasp on the site of putative monument on Spout Run .
The land owners address is freely available on the web , from that and relating it to the Spout Run itself (the site is just to the north of water course ) and the fact that the landowners property is limited to 200 acres provides a small area that also fits into the 205m height .
The important point is that from any of these points Bears Den Rock and even the hill on which it stands is not on the horizon .The actual horizon from the site ,on a bearing towards the rock /hill is only 105 metres distant .The figures are site - Bears Den Rock .alt = 4.81 i.e (205m – 377m at a distance of 1.98Km) ,site to local horizon =6.75 .i.e. 205m -218m at a distance of 105 metres = 7.33 .
There is a spot lower down at a height of 203 m that has the hill in view but not the rocks but this is quite a bit off the solstice having a declination of 21.86 which when considered in days is off by three weeks .
Eagle Rocks are in view from all points ,but as noted earlier , they are a huge target ,they occupy the horizon from 93 degrees from the site to 123 degrees and are meaningless as a marker .
The obliquity cycle is contained within the Milankovich cycles .

The Maes Howe alignment is to the winter solstice so you didn't miss anything ,and probably got better weather , although maybe not .
Yes the Ness is proving to be one of the major sites in world archaeology .and some of the stone balls one the most beautiful minor ones .
