I was taking a look at the CO spire measure list here:
http://www.peaklist.org/spire/lists/CO-50-abs.html
Maybe I'm not understanding something, but this list seems to have some holes in it. No Lizard Head, no Colorado National Monument, no Chimney Rocks, No Twin Peaks, No Turret Needle .
It does have North Maroon, and the Reduced Spire Measure list has El Diente - how does this happen?
