Just got back from a short vacation to Minnesota. On the way over, in the plane, I was reading John Noble Wilford's "The Mapmakers" (excellent read by the way, highly recommended). One of the places I visited on this trip was Pipestone National Monument, in the southwestern corner of Minnesota. Much was my surprise when I saw a sign there explaining about 2 of the cartographers who I had been reading about, and an inscription they left in the rock.
Rock inscription. Hard to make out, but some letters are visible near the bottom of the image. The real thing is a bit clearer.

Sorry they're so big, I tried to link them here as thumbnails, but that wouldn't work...
