Structures, Boulder Pile / Shelves
There are rock piles at each of the two ends of the U-Shaped quarry, both offering a similar dive experience. Begin your dive near shore and swim to one of the large piles of rocks. Descend and begin your dive. The rocks are piled steep and drop quickly to about 95ft in all directions.
Although this would technically qualify as an artificial reef, it has been in place for a considerable amount of time and much life has taken up residence on the pyramid like pinnacles of rock. Octopus, lingcod and rockfish fill most crevices between the boulders and a variety of stars, sponges, anemones and other invertebrates splash color on the granite rock. Mats Mats is moderately sheltered from current and can be dove at slack from an anchored boat.
Beware of boat traffic. This is an active quarry used by tugs and barges. Be mindful of your depth. Approach carefully and watch for submerged rocks.
How to get there:
Mats Mats Quarry is located north of Port Ludlow near Mats Mats bay on Basalt Point. Be careful when approaching the docks as there are many, many rocks submerged. Good anchorage can be found to the outsides of the rock piles.
The quarry itself sits between the dive sites of Colvos Rock and Klas Rock.
