It arrives here
Atlantic Ocean
Everything that falls here works its way east and north to the Atlantic. It is the drainage that carried the fur trade inland and the log drives back out, and the one Atlantic salmon and American eel still use — the eel travelling the whole length of it to spawn in the Sargasso Sea.

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.
