Altocumulus under a CONTRAIL and Cirrus

The Altocumulus in this photo are the puffy dense clouds from the left side to lower right. These are mostly Altocumulus because they are clouds with vertical development in the mid-levels but there are Altostratus visible in the lower right. Very high Altocumulus is found in the upper right along with a few Cirrus. The cloud elements are very small which means they are very high. Remains of a CONTRAIL (Condensation Trail) are visible in the upper center. It is water vapor condensing into water droplets or ice crystals from a passing jet aircraft.
