Cuexcomate, from the nahuatl "cuexcomatl" means "clay pot" or "place to keep". Its the smallest volcano in the world, with only 13 mts. elevation. Its in the middle of the city of Puebla. It was formed on 1664, by an eruption of the Popocatepetl, (an active volcano) with sulfhidric water, geiser and volcanic lava. There are even stairs to climb up into the crater. You can find that in the top of the volcano is a big leck (the crater).
There are stairs so you can decend into the volcano. At the bottom, you can see water, ashes and rests of volcanic lava.
