Worm marks.
Some of the pebbles practically
never were moved.
Others partially once let down,
by hunkering up & moderately
cleaned, when fine stuff
was washed out & coarse
grained material remained
behind.
Wind could not have
settled at once on pebbles
since time must have
elapsed sufficient for
growth of Crabs & Rhizids
otherwise,
A shoreline crack draws
away laterally,
a wind crack spalls off upward
at edges also.
To what extent do wave marks tend
to indicate the trend of the shore line,
or do they indicate wind direction?
In a shallow epicontinental
sea, it should be wind
direction.
