According to this site there is an AT&T Tower about 2 miles (as the crow flies) from MR's home. No other carriers have a tower in this area. I would imagine all carriers are routing through this tower in the area?

Here are the specifics on the tower...
Filing #: 2012-ANM-2671-OE
Latitude: 37.444
Longitude: -107.538
Structure Type: Tall Structure
Status: Unknown
Date Filed: 11/01/2012
Ground Elev: 8196.3 feet
Height Of Structure: 151.9 feet
Overall Height: 8348.5 feet
Structure Address: Not Recorded
So at under 200ft, it is an unregistered tower but with the elevation a 152ft tower should be adequate for the area.
I can't see there being no reception in the area, especially on a Monday morning when a lot of people are at work and the tower is not likely being overused.
