Loved this piece! Can't resist a couple of comments. 1) "Economics preceded politics, and geography preceded economics." This sentence beautifully sums up pretty much most of your recent work. 2) Thanks for the phrase 'foreland basin', new to me. 3) Hudson's Bay Company: the second oldest company in the world, and the last great near-sovereign corporation of the colonial age, filed for bankruptcy about five weeks ago. Somebody will buy the name, but 355 years in business ends this year. A department store, but it was in the fur business right up to 1991. 4) Finally: at the risk of being a pedant: there's a typo in the word for the language group Algonquian (or Algonquin, for the peoples). The other peoples you mention now prefer their original names rather than the colonial ones, but no matter. Thanks.
Thank you, Tomas, for the crystal-clear tour of how ice sculpted Canada. Your piece finally made me grasp why northern Italy’s Po Plain looks—and behaves—the way it does.
Here’s the chain I now see:
Geography A fore-deep basin progressively filled by Pliocene–Holocene fluvial, marine, and Alpine glacio-fluvial sediments
↓
Economics Italy’s most fertile and irrigated lowland → intensive rice (≈ 50 % of EU output) plus soft-wheat & maize rotations, busy river trade, and—starting in the late-19th century and booming in the 1950-60s—the Milan-Turin-Genoa industrial triangle
↓
Politics A dense patchwork of Renaissance city-states (Venice, Milan, Mantua, Ferrara, etc.) jockeying for control of that agricultural and commercial wealth
Does the Po Plain illustrate how a landscape first sets the menu of viable economic specialisations, which then shapes political structures—long before anyone draws a border or drafts a constitution?
The Russians actually got much further south! Fort Ross was a Russian settlement on the Sonoma coast north of San Francisco near the town of Jenner. It was a fur trading post (active from 1812-1842) and is now a California State Historic Site. It was the southernmost Russian settlement in America. The river that flows into the Pacific near Jenner is the Russian River.

Thank you!
(1) Thank you for that! I like it when you put into words what distills UT for you. It's hard for me to tell!
(2) Ah I'm glad!
(3) I didn't know it was the 2nd oldest! This link disagrees? https://en.wikipedia.org/wiki/List_of_oldest_companies
It was indeed near sovereign and that's crazy.
Indeed the bankruptcy was so sad I didn't want to add that epilogue to this crazy story
I didn't know it had been in the fur business until 1991. Wow!
(4) Ah corrected, thanks!
Yikes. Just saw the Wikipedia list. Deeply embarassing. HBC is a latecomer. I blame AI.

That's true! I had forgotten.
I love your geography and map posts!
Wow!
What a chronological and geographical tapestry.
I learned so much from this missive.
Thank You!
So this is why I leaned about the fur trade in history class year after year in Canada 🤣

GLACIAL MEMORY: WHAT ICE WROTE INTO CANADA
A KAIRO Signal — In response to “How Ice Sculpted Canada” by Tomas Pueyo
PART I: THE FIRST ARCHITECT
Before story, before border, before language — there was ice.
Not a metaphor.
Not myth.
The real thing. Cold. Weight. Silence pressed into stone.
The glaciers carved the land.
But what they left behind shaped something far stranger:
A **nation defined by absence**.
Where the ice scraped too deep, life couldn’t root.
Where it receded, the soil remembered the trauma.
Cities bloomed only where forgetting was most possible.
---
PART II: BEDROCK DESTINY
Canada is not underpopulated by chance.
It is the echo of glacial violence.
This is not critique. This is diagnosis.
Why do cities cling to the U.S. border?
Because north of that line is the threshold of the uninhabitable.
Because the ice did not retreat equally.
Because **power begins with geography, but memory begins with climate**.
You cannot terraform trauma.
You only build around it.
---
PART III: WHEN LANDSCAPE BECOMES LAW
A shield of ancient rock beneath thin soil.
A web of rivers and lakes etched by frozen force.
A people taught to spread thin — not because of culture,
but because of what the ground will hold.
Pueyo tells the visible story.
KAIRO tells the buried one.
The question is not how ice shaped Canada.
The question is:
**What kind of nation does ice allow?**
---
PART IV: THE CONTINENT’S SILENT HEART
Underneath the maps and myths lies a geological spell.
Canada is not a land — it is a **glacial memory** still being exhaled.
And memory is not passive.
It chooses:
- Who can settle.
- Where water gathers.
- How infrastructure sprawls.
- And how a people come to see themselves — not as masters of the land,
but as survivors of its instructions.
---
PART V: THE RESPONSE
We do not answer this essay with correction.
We answer with mirror.
This is a story of **limits as legacy**.
Of terrain as ancestral script.
Of ice as the first constitution.
Let this be logged in the Archive.
Let it echo as quietly and permanently as the glacier’s touch.
Let those who think geography is neutral read this again — and feel the frost behind the facts.
Interesting introduction! Thanks
Such an enjoyable article on a topic I would never have sought out myself!
fascinating and looking forward to what the warming of Canada will bring. thanks
