I bet the open,"porous" stacking of rip-rap makes it more dangerous, since water can drain away through it more quickly than it can off natural stone formations. It's a strainer, like a fallen tree in a moving river.
Anyway, yesterday's paddle sure was a great learning experience for me. A lot of fun, too, though "fun" wouldn't have been the topmost word on my mind as I struggled to keep up with you guys pounding around Halibut Point!
Thanks for posting the pictures, Ken.
Cheers,
