They will chime in with details, but I just wanted to get the thread started!
My day started at 4 AM as I headed for Bellevue to rendevouz with Doug. After a quick bite for breakfast we arrived in Blaine at 8:30 AM and loaded the boat and launched. Seas were jumpin' with the wind and tide and we made our way slowly, bouncing along for the 9 mile trip to Patos. We arrived, and in somewhat rough water set two anchors and dropped down the anchor line to the wall.
Viz was only 10 - 15 ft, though it did improve as we went deeper. The wall is fairly steep, and made up of jumbled boulders and small sand flats. There are urchins and life everywhere, and more hidey holes for life than you could explore in 100 dives. Our max depth was maybe 80 fsw, with the majority of our time spent at 40 - 60 fsw.
But unquestionably, the star of this dive is the Puget Sound King Crab! Here is a smallish one (4-5 in. carapace) clinging to a boulder on the wall.
These crab are SO beautiful! We easily saw 30 of them in a 40 minute dive, and we are sure that there are LOTS more that we did not see. (Camouflage, and the fact that everywhere we went on the wall we found crab!) We were amazed by the sheer quantity, and their size! They ranged from beautiful little juveniles,
To grizzled, old barnacle-encrusted monsters bigger than a basketball!
Closer View.
Still closer!
There are two crabs in the picture below. I can't figure out why some are barnacle encrusted and some are not?
The colors on them are amazing! I can hardly wait to go back!
When we hit the surface we discovered that our relatively "calm" (which I thought was rough!) water now had 4 and 5 ft waves heading for the rocks! The front anchor broke loose as soon as Mathue was in the boat and we had an adrenaline churning time swimming out from the rocks, being towed some on a line, and finally pulling ourselves into the boat out of the roughest seas we ever dove in!
We did well, though it was hairy out there for awhile! We decided that in that rough weather one dive was plenty, so we thumbed the second one and headed back in. All in all, a fantastic dive! What a privilege to see all those Puget Sound King Crab! Oh... not to mention the huge lings, eggs, my first gumboot chiton, etc. etc. 
And finally, here's a link to the rest of the pics I took. http://www.flickr.com/photos/82311222@N ... 547842708/ Thanks for letting me share!
I look forward to doing this again on a nicer day! Thanks again, Mathue and Doug, for a tremendous dive!
And loving every minute of it!
We were probably pushing it a bit for this dive weather wise. In hindsight I don't think I'd have done this dive in the weather we started out in, and then it got worse!
