Pacific Ocean
West, down some of the steepest drainage on the continent, and then straight into the Pacific. These are the salmon rivers: five species run up them from the sea to spawn and die, and the carcasses carry ocean nitrogen back into the forest.

Bedrock and soil figures are modelled from national geological surveys and global soil mapping, at a resolution of a few hundred metres — right for the shape of a district, not for a particular garden. River discharge is modelled, not gauged. For anything that matters, dig a hole and look.

The soil it made
What that means
The sweet spot for a vegetable garden. Nearly every nutrient is at its most available somewhere in this band, which is why it is the number every soil guide tells you to aim at.
Happy here without a fight
Almost everything: tomatoes, beans, squash, lettuce, apples, most perennials and most lawn grasses.
If you want the rest
Nothing needed. Compost keeps it here; heavy lime would push it past useful.
Working it
Fine and fertile, holding water better than sand without clay's stickiness. It caps over in heavy rain, so it wants a mulch or a cover crop rather than being left bare.
