Actors Jessica Biel and Emile Hirsch reached the summit of 19,340-foot Mount Kilimanjaro Wednesday – in just six days – making the trek to raise awareness about the global water crisis. In spite of the dangerous weather conditions, including thick snow and temperatures below zero, the entire 12 members of Summit on the Summit, a water conservation group, successfully made it to the top where most began the to cry.

The group was lead by the Ethiopian-born granddaughter of Robert F. Kennedy and included musicians, scientists and activists in addition to actors. Once the group reached the top they had to quickly make their descent, which was extremely steep and slippery. A documentary on the Summit on the Summit will be shown on MTV on March 14.
