Slip Point
Clallam Co., WA
Site Description:
This
site is on the north side of the Olympic Peninsula and faces the Strait
of Juan de Fuca. It is a rocky point that is like a shelf
sticking out into the water. On a good low tide the top of the
shelf is exposed. The rock is somewhat soft and there are crevices
and grottos carved out by the water. Thousands of sea urchins
also call this home and have carved themselves homes in the rock.
The shelf is very wave swept and it is not uncommon to find
deeper water species stranded up in the rocks. Be aware that when
the tide comes in, the shelf submerges with water very quickly.

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
Data is all intertidal unless noted.
