The Mariachi Trench is a large trench that appears in the comic strip They're Playing My Tune.
It is a very deep canyon with gray rocky cliffs on the sides, several rocks scattered across the ground, and a sandy bottom. A small mariachi band lives in the trench, which explains the trench's name.
Role in comic
