In the Apennine mountains we have several interesting features. These include the crater Conon, Mt. Bradley, Rima Bradley and Rima Hadley. Conon has steep internal walls, is 11 miles in diameter, and has no central peak. Mons Bradley rises about 14,000 feet above the floor of Mare Imbrium. Rima Bradley is a long depression, a graben-type rille, caused by land that has sunk between parallel faults. Rima Hadley (Hadley Rille) was most likely caused by a lava flow or collapsed lava tube. 
Go to NASA site to see video made by Apollo 15 astronauts as they flew to Hadley Rille in 1971.
