And now I understood why Cadboro Bay is so shallow under that bluff when it's deeper along the east shore -- under the bluff here is like the shallows south of the bluff at the end of James Island. The sand slumps. It's been slumping since the glaciers retreated at the end of the latest ice age. When I paddle over that shallow, sandy-mud bottom, I'm paddling over ten thousand years of sand slumping into a basin scoured between the bedrock of the east shore and the bedrock of the Uplands shore along the west and south. The tides pull the sand out and spread it along the beach between the arms of the bay. There's been a sandy beach here for ten thousand years. That's only a heartbeat in the geological time that Dr Yorath the geologist showed me how to see. But it's all the time that the Salish-speaking people have lived at this end of Vancouver Island.
I drifted on for a while, paddling slowly. Flower Island was living up to its name, all a-bloom with blue camas flowers. This island was someone's place to gather camas bulbs for special feasts, right up till a hundred years ago or so. This basalt rock would have been connected to the point ten thousand years ago. The narrow channel that separates Flower is also a shallow one. I took my boat around Flower to Evans Rock, where there's another channel, shallow at low tide. John took this photo of a seagull and two oystercatchers there.
