The lower-driving snow piles up in mounds and
ridges wherever it meets with obstructions such
as fences, stone walls & banks. Some of the drifts
are many feet in depth and almost as hard
and close-grained looking as fine marble. The
wind works ceaselessly at them while it lasts,
modeling and sculpturing them into exquisitely
beautiful forms and curves. They may retain
their beauty for a week or more but ordinarily
it is obscured by another snow fall or ruined by
a thaw, in the course of a few days.
