Linda McElroy first noticed vertical-sided rock piles

The first published reference to vertical sided piles is from 1999 in my article "An Array of Rock Stacks in Acton Massachusetts" where I say: "Linda McElroy pointed out that many of the piles have this single steep side. " (there is an illustration).

The article is at http://www.neara.org/WAKSMAN/stacks.htm but I believe it also was printed in a NEARA Journal.
