Larry Harrop posted on his blog a short article that I put together on the Smith farm. You can find it at http://www.rock-piles.com/Smith_Farm/index.htm.
Update from Norman:
Jim would like to see some references to the statements I made in my web article on an unusual crescent-shaped cairn in . I'm listing them below.
My main source for maintou stones is James Mavor, Jr. and Byron Dix's Manitou (Rochester, Vermont, 1989, 332-342). While their focus is on the 'head and shoulders' type, I believe the kind that I have found in is also typical. Another discussion of manitou stones, this time in Wisconsin, is Herman Bender's article "Manitou Stones in ." NEARA Journal 33 (1999), 80-83.
One of the best and most recent discussions of quartz is found in David S. Whitley, et.al, "Sally's Rockshelter and the Archaeology of the Vision Quest," Cambridge Archaeological Journal 9:2 (1999), 221-247. Quartz is duscussed on pages 225-235.
Another source is David Whitley's The Art of the Shaman: Rock Art of , , 2000.
Paul Devereux, whose books often are very New Agey, has written a fascinating and sober book about sacred places, titled The Scared Place, 2000. A discussion of quartz is found on pages 128-132.
I have a lot of other references too, most in hard to find journals. The term "frozen light" comes from , the prolific Roumanian historian of religion, in his book Shamanism: Archaic Techniques of Ecstasy, Princeton 1964.
