Very Large Rock , Boulder Pile / Shelves


A small ravine leads from about 20ft to a huge boulder that extends nearly to 100ft at its deepest point, thus the name 100ft Rock. The rock itself is a glacial erratic, meaning it was deposited here long ago by a glacier. It measures about 20ft high and 30ft long with lots of crevices and surface for sea life to take shelter. Small anemones and zoanthids cover the rock and provide shelter for a variety of sculpin. Rockfish, perch and greenling swim around the perimeter of the rock. The ravine continues below the rock to beyond recreational diving limits. Upon return, gunnels make homes in the pitted sandy/clay shelves on either side of the gully and among the wood and debris that have settled in the depression. Ambitious divers enjoy exploring below the marina though it is quite a long swim from the rock.

Special Restrictions:

Some current may be present during large exchanges but is not sever in the ravine or on the rock. Makes sure it is calm enough to return to your boat.

This site was once accessible from shore by walking down the railroad tracks and down a rustic little set of stairs to the water. There is now a no trespassing sign posted, disgruntled neighbors intent on reporting divers, and stiff penalties imposed on those who disregard the warning so it is no longer advisable to attempt this from shore.

How to get there:

100 Foot Rock is a few miles north of the Edmonds Ferry dock near Meadowdale. To locate the rock, anchor a couple hundred yards south of the old marina in safety-stop depth range. There is commonly a white buoy just north of the gully that may help encounter the starting point. Descend to about 50ft and turn south. Continue until you reach the small gully with small sandy ledges (the depression from the gully can also be seen from the water surface as a depression on land). Turn west and follow the gully downward until you encounter the rock in about 70-75ft.
