Here’s the AM band scan from my time in west Texas. I wasn’t able to check every frequency both night and day, partly because AM was hampered by bad RFI at the hotel, which required me to go outside when I could.
I mostly used a CC Skywave and occasionally a ’14 Accord stock radio or Sony 7600GR. Below I’ve indicated the general time of day for each reception. All stations were heard in Alpine unless otherwise noted.
