Graham`s Wall - Pacific Northwest

Graham's Wall, in the PNW, is one of those dives that always leaves us feeling a little more connected to the wild, rugged spirit of the Pacific. It's a proper wall dive, dropping away into the deep, and it truly showcases the robust, often overlooked beauty of cold water. We love the sheer scale of it, with cracks and crevices offering homes to a surprising density of life. Our favorite part is the macro stuff, particularly the shrimps. You'll find Pandalus eous and Pandalus danae tucked into every overhang, alongside the California Spot Prawns. Keep an eye out for Daubed Shanny, too. They blend in so well you might miss them. The Red Sea Urchins add splashes of color against the dark rock. While you might spot the occasional Spiny Dogfish patrolling the deeper sections, it’s the smaller, more intricate life that truly shines here. We'd suggest going on a slack tide to really appreciate the details, as currents can pick up. It's a dive that rewards slow, deliberate exploration.
