Hudson Bay Seaboard
It arrives here
Hudson Bay
An enormous, cold, inland sea is the destination — water from here flows north rather than south, which surprises most people who look at a map for the first time. It is ice-covered for much of the year, so the whole system is on a short, violent, snowmelt-driven schedule.

normalAbout what it should be for the date. The river is doing its ordinary work — sorting gravel, feeding its banks and moving fish around at the pace everything in it is adapted to. It is dropping, roughly 37% over the week ahead.
Under your feet
About 2.8 billion years old — older than free oxygen in the air, and older than almost any fossil.

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
Water runs straight through, so it dries fast and warms early — you can work it days after rain and sow ahead of heavier ground, but it needs watering and feeding more often because both wash out.
