Arizona County Low Points

Compiled by Scott Surgent, proofed with additions by Andy Martin

This is a table of the lowest points of elevation within each of the fifteen counties of Arizona. Without fail each of the "county lowpoints" occurs along a river where it leaves the county. The famous Colorado River provides the lowpoints for four counties (Coconino, Mohave, La Paz and Yuma), while the Gila River provides the lowpoints for three counties (Greenlee, Pinal and Maricopa).

Each lowpoint is linked to the maps.

Andy Martin checked this list and pointed out some fixes and alternate areas, which have been included here (updated Oct 31, 2007).

I daresay that standing on all the lowpoints is a much more difficult task than standing on the fifteen county highpoints. Thus far I am 0 for 15.
