Using a clam shovel...
First look for a "clam show". What is a clam show?
That's where a clam has withdrawn its neck or started to dig leaving a
hole or dimple in the sand. There are three major kind of "shows" to look
for:
- dimple: a depression in the sand
- doughnut: which has raised sides
- keyhole: which is usually in drier sand areas and is shaped
like an "hour-glass" or is a hole with very distinct sides.
Always look for the larger sized hole shown here next to a quarter. This
is a good indication that the clam will be larger, but not always.
Clams will also show at the edge of the surf line when you pound the
beach with a shovel handle or your foot. They may squirt sand and water
out of the hole where they are located. You need to be quick when digging
in the surf as razor clams dig quite fast in the soft fluid sand.
