West Anhui Rift Valley 皖西大裂谷
The West Anhui Rift Valley, formerly called Biwangyan, lies in Zhangdian, Jin'an District, Lu'an, Anhui. It is a long, narrow cleft in the conglomerate hills on the northern flank of the Dabie Mountains. The walls are sheer, in places so close that one person can barely squeeze through sideways; a stream runs along the bottom, crossed by walkways and wooden ladders.
