Site Description:
This
site is on the north side of the Olympic Peninsula and faces the Strait
of Juan de Fuca. Most of the beach is sand with some gravel
and a few large boulders. The west side of the bay is all rocky
and is also covered in algae and seaweed. The point at the
northwest edge of the bay consists of large rock outcroppings.
The following species list also includes subtidal species found

Species List:
Following is a list of mollusk species observed at this
location by members and associates of the club. This is by no
means a complete list of the species which may occur at this site.
Revisions and additions to the data are made as we acquire new
information. When a site contains more than one very distinctive
type of habitat or if multiple sites were included in a single
location, then a
species list for each is included.
We indicate
frequency of occurrence based on our observations. This is an
indicator of how likely it is that you may be able to find this
species yourself and is not a formal population survey.
Frequency Code:
(Based on the assumption that you are looking in the appropriate
location where the species
likes to live - on rocks, in
sand, etc. Some populations fluctuate seasonally. Ours are based
on the spring/summer seasons.)
[4] - Rare - very difficult to find, maybe only a couple found after repeated visits to the site
[3] - Uncommon - difficult to find, may not see on every trip but dedicated searching may turn up a few
[2] - Common - easy to find, should locate a number of them on any given day
[1] - Abundant - very easy to find, large numbers should be seen on every trip
The
frequency rating only applies to the intertidal data. The
subtidal list is incomplete and due to the nature of the data, is not
rated for frequency.
