I do not know if the data exists, but every State has a county or county
equivalent. The independent cities (30 some) in Virginia are county
equivalents, that is, first order civil divisions of the State, and equal
to the Virginia County (there are also one each independent cities in
Maryland, Missouri, and Nevada). In Alaska, the Boroughs are county
equivalents, and the unorganized area is, in fact, organized into Census
Districts, which are county equivalents. Also, the Parishes in Louisiana
are county equivalents as well. The peculiar New England situation is
relevant only in New England. Specifically, the Towns (not like towns
anywhere else except to a degree in New York, Pennsylvania, and New Jersey)
are still considered second order civil divisions of the State, and the
county (even if it's government is non-functioning or even abolished) is
still the first order civil division. Also, the territories and
Commonwealths have county equivalents.

I would be very surprised if anyone has compiled such data for the 3,000
plus counties of the U.S. First I can see no reason for compilng such
data other than to get a few extremes so someone can brag about their
county being low, high, flat, or rugged. Second, there is great variation
in the size of counties across the country which would make the comparison
of any numbers rather meaningless. Third, what are you going to do those
places that do not have counties, per se, such as Alaska, Connecticut,
Virginia?
These criteria might have meaning relative to watersheds, but I can see no
value for political entities such as counties. I hope this is not someone
who wants to try to relate a few physical parameters to social or political
values to explain human behavior.
