The Tucson Valley CBC Circle Map

On December 14, all bird observations will be compiled and summed up for the Tucson Valley Christmas Bird Count. But for anything to count in the totals, it must be observed within the boundaries of this 15 mile-diameter circle, which was defined in its current location centered near or at Oracle and River Roads in 1971 (though it has been wiggled around several times since then)
