Mons Hadley is a
massifIn geology, a massif is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term is also used to refer to a group of mountains formed by such a structure...

follows a course generally to the northeast, toward the Mons Hadley peak, for which it is named. This feature is centered at selenographic coordinates 25.0° N, 3.0° E, and lies within a diameter of 80 km. It begins at the crater Béla, an elongated formation with the long axis oriented to the northwest.
