Today, there are many routes on the wall, ranging in length and difficulty. The classic "Rimmon" and "Swedish" routes were normally free climbed in a day or two until being heavily damaged by the 1998 rock falls. The longer and more engaging aid routes, such as the 1972 test piece "Arch Wall" (climbed by Ed and Hugh Drummond in 20 days), or the 1986 "Death to All/Pretty Blond Vikings", which cuts through the steepest part of the wall, require advanced knowledge of big wall climbing and several days on the wall.
