M.F. Smith 1980 JOURNAL Albuquerque, New Mexico May 18 Pulled in the live traps by midmorning. Drove down another mile or so to see the rock arch that a local rancher had told us about. If the animals on the two sides of the lava flow differ karyotypically and genetically as we expect, then there would be potential contact between the two forms around the southern end of the lava flow, or across the narrower parts near Grants. We drove back to Albuquerque and Jim and Carol dropped me at the airport for my flight at 2:45 PM.
