I found two: 32.807001, -111.722184 and 32.791790, -111.705250 I'd like to find more to see the 'grid' mentioned in the article.

The description there implies that the other crosses no longer remain, but I was able to find the first 3 I looked for just by looking for midpoints between other markers on the grid.
