Geography and Geology
The canyon is framed by significant Andean peaks, with notable mountains such as San José, Maipo, and Marmolejo, the latter being the southernmost mountain exceeding 6,000 meters in altitude globally. These mountains contribute to the dramatic topography of the area, and several are active volcanoes, with the San José volcano having last erupted in 1960. The geological processes of river erosion have been the primary force in shaping this impressive valley over millennia.
