Pottery of the time was low-fired and did not generally reach vitrification, and it was not glazed with a silica-based glaze that would seal it.
So over time this pottery would absorb water. And especially low-fired bits could totally break down.
Source: amateur ceramicist, and I have first-hand experience with cone 6 clay (vitrifies at 1200c) bisc-fired to cone 04 (1060c) and crumbling to bits when left in water too long.

to add some context, in modern gardening things like crushed vermiculite are a common soil amendment. being a porous absorbent mineral, it serves the same purpose.

Not to mention terracotta is a very common material for potted houseplants and container gardening. Terracotta is low-fired, non-vitreous and porous to water, giving it nice breathability and water absorption characteristics.
There are also long-necked terracotta bottles (called ollas) you can buy (or DIY) which you bury in the ground. You fill the bottle with water and the terracotta itself acts as a wick, providing a slow release continuous underground water source for plants to access.

I seem to recall one or two doing this. But i suspect the reason they don't is cause they don't need to.
They all have a pot already. The benefits of more pots seems low. Conversely the calorie cost seems high (if only just collecting clay and cutting wood to fire it.)
On Alone thd priorities are shelter and food. Clay pots seems like a luxury in terms of utility use and energy cost.

This is the correct answer. Alone is not really a how to live in the woods show, it's a managed starvation show. The contestants are limited to about a 1 sq mile area which may or may not have a good source of clay. They purposely set them out just a few weeks before winter so they do not have a long time to prep. Conserving and replenishing calories is the name of the game.

Most of them did a simply terrible job of building a fireplace, from poisoning themselves with the smoke to literally burning their shelter down. Some built a bed up off the ground, which is smart, but never seemed to consider heating up rocks in the fireplace during the day and slipping them under the bed at night.
Anyhow, some mud and clay skills would help make a decent fireplace.
Staying warm is a crucial skill, not a luxury. Some of them got frostbite.
Also, most of them had food storage problems where their meat would get robbed. Some went to great effort to make their meat inaccessible, to no avail. I imagine that would make a storage pot useful.

If you try to make a planting bed in any settlement that’s more than say 100 years old on a site that was continuously lived on, you are guaranteed to come across at least some shards of glass, pots, plates, etc. Even if the spot was never explicitly a trash mound. Things break, people usually try to pick them up and put in trash, but (especially in grass) miss pieces. When kids break stuff you often don’t want them picking up sharp objects. Things get stepped on and pressed into soil. Many many reasons to find pottery shards where they seemingly don’t belong.

The problem isn't "because it was caused by humans" per se. Invasive species because of the speed they migrate.

You'd be surprised but the "landraces" e.g. historic geographically constrained cultivars tend to do better than modern cultivars in certain geographical regions. A modern even GMO cultivar might have a couple of beneficial traits introduced over the course of a few decades of work. Whereas a landrace might have been selected for yield in that area for a thousand years or more, maybe 100x or more as many generations under selection. As such there is a huge interest among a subset of biologists today to catalog all of these remaining landrace crops and the genetic diversity they contain before they are lost, either due to changing climate wiping out their native environment or the modern farmer replacing these cultivars with ones you can buy in bulk quantities from your seed supplier and have more of an export market (some landrace crops aren't fit for export shipping due to fragility of the crop unlike more modern cultivars; bananas are a good example where there are 1000 types grown but only 1 single varietal particularly fit for overseas shipping hits the supermarket).

It doesn't take many generations for selective breeding to show improvements in landraces. Even just making sure that volunteers from seeds that were thrown out as food waste were given a chance to fruit and seed starts that process.
One of the more interesting sources of landraces can be found in local seed saving programs, such as ones hosted by local libraries. They are more likely to be viable seeds that is adapting to the local conditions.

Corn is grown in the UP with current varieties currently.

It didn’t necessarily need to be highly productive, just more productive than cultivating local stuff, and even if the corn was not necessarily at its most productive it might have been worth it (and with no real replacement) as part of the companion garden, getting just a few ears of corn would still have been worth more than unproductive wooden stakes.

Or, they had far advanced knowledge of working and remediating soil to grow food. Peat mosses, charcoal, household compost, are all valid soil additives that we now have scientific knowledge to explain how those benefit soil, but they were practicing it in soil that is otherwise unproductive. Given that no one else farmed it in that time it seems that knowledge was lost, but lines up with regenerative agriculture practices we see today.

It's not really random. Disease development in the Old World was a combo of long term urbanisation and animal husbandry.

Hundreds of thousands or even millions of years of eveolution of diseases that evolved in Africa/Eurasia pretty much gets purged during that migration.

Agreed, but this tradition of speculation had been around for decades before researchers figured out just how severe the plague toll had been.

According to graphs I’m seeing, it looks like it was warmer for a period, but then cooler until now. They would have been farming here during a cool period.

A while back it dawned on me that we think the greatest past civilizations were all in Egypt, the Middle East, and Mesopotamia because those areas are deserts or semi-deserts. They built out of stone because they didn't have much wood, and their writings survived because they weren't destroyed by water.
There could have been very sophisticated societies, even large scale civilizations, in the past in places like North America that built mainly out of wood, clay, bone, and other readily available materials, and there'd be nothing left. Any writings would be gone too, since writings don't survive well in wet climates unless they are chiseled into very durable stone or vitrified pottery (and even then they can erode).

Imagine the archeological excitement by your bus stop if a preserved part of the farm from 1,000 years ago were discovered, barely disturbed, giving archeologists a snapshot of what daily life was like at the time.
You know also know the story of Pompeii, and how its ruins have helped understand the Roman era.

The article would appear to suggest that the farm was established near the beginning of the Medieval Warm Period and abandoned near the beginning of the Little Ice Age... which seems incredibly unsurprising.
> They would have been farming here during a cool period.
I see no indication of that.

There is a theory that the Little Ice Age was precipitated by the reforestation of land in America as the natives died off from exposure to European diseases. And of course, there's always the theory that it's just something that happened.
More from that same page:
It’s also kind of amazing that the fields stayed preserved for a thousand years. Makes me wonder if we’re still underestimating how advanced some of these early farming cultures were.
There could have been very sophisticated societies, even large scale civilizations, in the past in places like North America that built mainly out of wood, clay, bone, and other readily available materials, and there'd be nothing left. Any writings would be gone too, since writings don't survive well in wet climates unless they are chiseled into very durable stone or vitrified pottery (and even then they can erode).
In the Middle East they probably think that's short too!
My watching of years of Time Team episodes tells me that Roman mosaic floors keep being found in England, like https://historicengland.org.uk/whats-new/news/rutland-roman-... from about 1,500 years ago. Doing so makes the news.
These floors, and the ruins around them, whilst buried, don't always survive the last century or two of machine plowing, which goes deeper than the medieval animal-based plowing.
Imagine the archeological excitement by your bus stop if a preserved part of the farm from 1,000 years ago were discovered, barely disturbed, giving archeologists a snapshot of what daily life was like at the time.
You know also know the story of Pompeii, and how its ruins have helped understand the Roman era.
This story is likely somewhere in between those two. Unlike your bus stop farm there aren't written records from the 1,000 years ago, nor are there many other sites from which to draw comparable results.

Clearly it was logged for a while, and perhaps they were expecting to cut it down again at some point.
And then much of the logging the UP is selective harvesting rather than clear cutting, so they go in every so often and take out the larger trees.

Oh, was this mentioned in the original HN title? Has that been edited?
Yes, it was. https://web.archive.org/web/20250615154352/https://news.ycom...
Original HN title was "1k year old 3 sisters crop farm found in Northern Michigan"
I really wish that when titles were edited there was some history, it would make it much easier to understand these little discussions based on the original title.
It's surprising ("I'm shocked, shocked, well not that shocked") how this style of farming somehow made it all the way to my ancestral village for cultivating these New World crops.
Gotta love proto-globalization.
