"Branching off the main Goma-Bukavu road on the shores of Lake Kivu, an earthy track climbs high into the mountains of Africa's Great Rift Valley, switchbacking incessantly through the lush green landscape before eventually reaching the mining village of Numbi. Small cassava plantations and human dwellings dot the hillsides along the way. Groups of women can be heard singing as they journey to market." (Quoted from article)
