After logging the 'Years Ago' cache, Mrs. spotted something out of the corner of her eye that she said looked like some sort of headstone. We were glad we took the time to check it out since it turned out to be a USGS marker for three benchmarks clustered right out in the middle of nowhere. We found one... then another... then another. Now that we're home & have access to the computer, it would appear that we got 'em all.
