Of all the ruins in Mesa Verde National Park only 28 have been named and
only 30 excavated. No survey of the unexcavated sites has been made, and
the total number of ruins is unknown. Several hundred cliff dwellings
have been discovered, and new ones will probably be found in the more
remote canyons. The surface pueblos outnumber the cliff dwellings, and a
careful search would reveal many that are now hidden by a thick growth of
underbrush. The earth lodges of the Late Basket Makers are so common that
hundreds will be brought to light by careful search. Dozens of them can
be located in a half-hour walk over any of the mesas.
