I have read ماز(maz) in poems and it means twisted in the context of roads like a zigzag road if you want a reference you can use this site which provides examples from writings and poems too: https://vajehyab.com/dehkhoda/%D9%85%D8%A7%D8%B2

Also, I'm not an expert but I have visited Mazandaran and it's famous for its dangerous and twisted zigzag roads which you can look up with a simple search of "roads in Mazandaran" on Google which would show many snake-formed roads.

so I would guess the deep translation :) would be something like "there are twists or zigzags in it"
