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.
