Frequently we invaded these ranges thru deep chasms or canyons with sides measuring thousands of feet high and with only enough room for the wing tips to speed by without touching either of the opposing side walls. These clouds certainly have a quality of depth or inward penetration that is not descernible from the ground aspect. At a distance these barriers appear impassible but distance always has a power of compacting a cloud mass that is in reality loosely constructed. As one approaches the continent unique cloud formations lése their uniqueness and oneflys again over loosely arranged fracto- cumulus below. I am sure that these complex cloud formations are only peculiar to extensive water masses. Departing reluctently from this Pleistocene world we dropped slowly to the terra firma.
