The Great Rift Valley - a vast crack spanning the length of East Africa - is the product of deep-seated geological forces which have spewed out a line of cloud-wreathed volcanoes stretching from Ethiopia to Tanzania. Their peaks provide a refuge for East Africa's most extraordinary wildlife, including newly discovered and never before filmed species which have evolved surprising survival strategies to cope with their challenging mountain environment.
