geology map of the Flagstaff area

Sometimes a geology map contains too much information.  The following map is the same area as the
one above, but all of cultural data and streams have been painted out.  It is no much easier to see the
distribution of cinder cones (asterisks) and lava flows (2 types of pink).

Using Google Earth the positions of volcanoes are highlighted.  More than 350 cinder cones, some
fresh, some weathered, are identified.  More volcanoes were observed than whaty was included on the
geologic map of the area.
