G.B. Church - Pacific Northwest
G.B. Church. Now, this is one of those spots in the Pacific Northwest where we’ve found ourselves lingering, sometimes just floating, watching the world go by. It’s not about dramatic drop-offs or massive pelagics here, though we have seen the occasional orca pass through on a good day. For us, G.B. Church is a macro lover’s dream. We often drop in, the current usually a gentle nudge, and settle in for a slow drift. Keep your eyes peeled on the substrate. You’ll find Plainfin Midshipmen hunkered down, their bioluminescent organs sometimes giving a subtle glow. We’ve spent whole dives just combing through the anemones and hydroids, finding Roughpatch Shrimp and those tiny Four-Spined Squat Lobsters clinging on. The sweet potato sea cucumbers are everywhere, their tube feet working overtime. It’s a site that rewards patience, a slow pace, and a keen eye. Bring a good dive light to pick out the colours and textures, especially those vibrant green sea urchins. We love G.B. Church for its quiet beauty, for the intricate lives playing out in miniature right in front of you. It’s a perfect dive for photographers or anyone who appreciates the smaller wonders of the cold water.
