The team with Prof. Joger left Braunschweig on 1st March 2007. They had an exciting 20 day trip. They had to cross a mine field, came across a saw-scaled viper (one of the deadliest venomous snakes in the world) and had to change a tire in 39° heat. They also visited the Mosque of San in Mali (built entirely from clay). On 18th March the team crossed the Niger river and reached the semi-desert. Two days later they arrived at the excavation site where the rest of their team was already waiting.
