What this list doesn't know

Shade from the surrounding terrain is counted where we've measured it, which is most of this list — the rows marked aspect only are the exceptions. For those we use the direction the wall faces and nothing else, so a wall deep in a canyon may be shaded by the opposite rim long before this says it is. Even where terrain is counted we measure the skyline within 3 km and work from bare ground, so trees on the rim and a distant range are not in it.
1,012 of 2,256 Colorado crags have no aspect on record, so they can't appear here. A crag missing from this list has not been checked and found unsuitable — we simply don't know which way it faces.
Sun is not the same as warm, and shade is not the same as cool. Altitude, wind and the day's weather decide that. Check the crag's page for current conditions before you drive.

Wall directions come from a guidebook where one says so, and otherwise are measured from USGS elevation data. How sure are we?
