Harvey Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Harvey Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Harvey Rock is classic Alaskan cold-water diving, and we mean that in the best possible way. The site is a rocky outcrop, and the real stars here are the invertebrates and the larger, more unusual fish. We’ve had good luck spotting things like Spiny Dogfish and the occasional Big Skate cruising the perimeter. Look for the striking red soft coral clinging to the rocks and the massive Sunflower stars slowly making their way across the substrate. It's a spot for divers who appreciate the subtle beauty of a northern ecosystem rather than a riot of tropical colour.
Safety Notes
