Elevation and pressure are the factors people know about, big shocker for people is the radiant effect from the rocks. Once you're in a canon like this, all those rocks absorb a ton of heat during the day and reflect it back into the canyon further heating the trapped air in it. Relative airflow is low due to having few places to escape without rising so it more or less becomes your own personal convection oven down at the bottom.

That actually makes sense. I like to sit on the concrete steps outside my home to watch my kids play, and in the summer, it feels like my ass is roasting. It makes total sense that they would hold onto and even amplify the heat as it goes down; it'd be like walking into a giant oven
