A quadripoint is the meeting of 4 territorial boundaries at 1 point. For the given entities (leftmost column), select the 4 sub-entities that make up the 4 corners. 2 unused answers per column.
DISCLAIMER: Some of these may not be exact by a couple o' hundred meters, but given that the circumference of the Earth is over 40 million meters, I ain't sweatin' it. (If the 'no quadripoints' selections are in play, it'd be by a lot.) TRIVIA: Montezuma County is involved in 2 of the quadripoints of this quiz, although is only the correct answer to one!
