8.3.3 Snow Boards
Snow boards (see Figure 8-3)
are laid on top of the old
snow when there is any
possibility of new snow
falling. They may be made of
thin lumber or other light
material that will not sink
into the snow, yet be heavy
enough not to blow away.
They should be painted white.
Push them into the snow just
far enough that the top of the
board is level with the top of
the snow. A 24" X 24" snow
board will allow cutting more
than one snow sample. After
each observation, boards
should be cleaned and placed
in a new location. Because of
evaporation or drifting, they
may need adjusting daily to
assure that the top of the
board remains flush with the
old snow.
