Chris, eerie when you are down into it, and strange when you come upon it. It's an unusual submarine canyon because the edge of it at one point is only a couple hundred meters from shore at a place called Moss Landing. I wasn't sure what we'd find kicking out to it, would it be a gradual incline or a sheer drop off? Where we came upon it, it is in fact a kind of drop off ledge that just abruptly starts, but the bottom in that area on up to the ledge and on the sides was sandy gravel like, not a totally vertical ledge, but a steep enough angle like about sixty degrees, that as I mentioned, the sand on the sides was perpetually sliding down into the void. Neither of us had ever dove so deep. My friend went on to become a dive tender, mostly working on oil rigs all over the world. His brother became a professional diver also on the rigs. The trench dive is a cool memory in my mind.
