So, this is the western-most piece of the "arch". Sad that it appears to have been broken.
Well, if the plane of the arch is oriented E-W, and it's vertical, as it appears tobe, then the normal to the plane faces North, though no to Polaris. He equinoctial; sunrises and sunsets would also be due East and West, so in the plane of the slab.

It consists of three pieces at sites along the Canada-USA border (Campobello NB, Point Roberts WA, Lake of the Woods, MI) and together they are meant to represent a conceptual arch symbolizing friendship between the two nations. The 3 sites are geographically interesting - they are reachable by land from the main part of their respective countries only by travelling through the other country (pene-enclaves). I was recently at Point Roberts and saw the piece located there.. There is a plaque indicating that the piece is aligned to the North Star, the equinoxes and the solstices. I found that the plane of the slab forming the sculpture is aligned East-West but I could not see anything that matches the other directions mentioned. Am I missing something? Perhaps the shape causes a special shadow on the special dates? You can find photos on the Web, for example at http://2.bp.blogspot.com/-t9hlFDU5te0/UzWerhh1YLI/AAAAAAAAmQg/7gPHFqa8TFw/s1 600/Pt+Roberts+Sunsweep.JPG The outer (upper) curved edge has a curious V profile, with the point of the V switching from one side of the slab to the other as it progresses over the length of the curve. The inner or lower curved edge appears to be perpendicular to the plan of the slab. I could not see any markings on the ground. To me, placement of the ring of stones around the base appears insignificant. Any thoughts?
