Somewhere in Arizona or on an Indian reservation as they are in Mountain time but they don't observe daylight savings.

Definitely Arizona. AFAIK nowhere else does MST without DST. And the photos both appear to be of places in Arizona. Fun fact, within AZ, the Navajo Nation does DST while the rest, including the Hopi Reservation enclosed by the Navajo Nation, does not.

The site owner appears to prefer privacy so I’m not gonna speculate any further.

The Yukon recently moved to MST without DST (to ditch DST)

TIL thank you! I am so glad the no-more-DST train is finally picking up a bit of steam.
