Any suggestions?

No it's not on a thermostat. Where is the best place to get them from? I have like 3 layers of paper towels where the UTH is.

This would explain why your snake is picking the worst hide in the tank to take refuge.
Either regulate or unplug the UTH before you cause any harm and hope you already haven't.
Paper towels don't stop the heat and your snake can burrow.
120+ degrees is not their ideal temperature, get a temp gun and either a thermostat OR dimmer and cut it back to 95 or less.
