From the 16th of June to the 1st of July 1999 the expedition Hatun Mayu (meaning Big River in Quechua) explored the source area of the Apurímac River in southern Peru. The seven member expedition was lead by the author of this article, a member of the Faculty of Science, Charles University, Prague. The aim of the group was to measure the lenght of the main source of the Apurímac River currently considered by most hydrologists as the longest source segment of the Amazon. In addition, the expedition members maesured flows and altitudes in order to create the lenghtwise profile of the Río Carhuasanta stream.
