A Range Overlap of the Pinyon Pines in central AZ

In which mountain range could one find three different U.S. Pinon Pine species (P. cembroides, P. edulis, and P. monophylla)?

Trick question!

Surprisingly, not a major mountain range, but the low hills surround Aravaipa Canyon.  This area may be an important biogeographical linkage between the sky island mountain ranges to the south, dominated by Mexican Pinyon (Pinus cembroides) and the larger mountains to the north, dominated by Pinus edulis.  Pinus monophylla is more of a Colorado plateau and California mountain species, but with weird disjunct populations as far South and East as the Florida mountains near Deming, NM!
