I was in the Phoenix & Tucson areas after Thanksgiving, so I had some time to scan the bands for activity...

And we made a quick side trip up to Kitt Peak. The National Science Foundation vehicles all carried VHF hi-band antennas and I may have caught some of their radios with the Close Call, along with other transmitters located up on the peak:
155.6250, D343 - May be some sort of bus service or school district.
164.3500 - NSF Operations at Kitt Peak
165.2375 - Definitely a CBP Customs NET 1 repeater up there!
168.5250 - NSF operations on Kitt Peak
859.0000, D025
860.0000, D025 - Don't know who these two conventional repeaters belong to, but they were definitely located up on Kitt Peak.
