Lost Canyon, a southern tributary of the Dolores River, contains
instructive cliff-houses to which my attention was called by Mr. Gordon
Parker, superintendent of the Montezuma Forest Reserve, who has kindly
allowed me to use the accompanying photographs. This cliff-house
(pl. 10, _a_, _b_) belongs to the true Mesa Verde type and shows
comparatively good preservation of its walls, some of the beams being
in place. It is most easily approached from Mancos.
There are small cliff-houses in the same canyon not far from Dolores,
but these are smaller and their walls very poorly preserved.
An interesting feature of these cliff-houses in Lost Canyon is that
they mark the northern horizon of cliff-dwellings of the Mesa Verde
type, having kivas similarly constructed.
