Image Caption: Ringed by mountians, this basin, averaging over 2400 meters in
elevation, is an example of an interior drainage system created
by a volcanic landscape. Swamps or marshes (1) develop in the
low areas, and water levels fluctuate greatly with the seasons.
The better drained land is cultivated (2). Eroded volcanoes mark
the landscape (3). The snow- capped stratovolcano, Pico de Ori-
zaba (4), last erupted in 1687. Note the difference in vegeta-
tive cover between the mountain slopes and the basin floor.
