Owl Acres formed a tiny part of the tall grass prairie that evolved after the last glaciers receded. As such, it would have seen the changes that made mammoths and other giant wildlife extinct and the rise of native hunter-gatherer groups. For over 300 years prior to European conquest, a group of tribes collectively known […]

Grass seems to be everywhere. On Owl Acres, it covers the yard around the house, the open spaces around the barn, and the ditches along the road. Most of the species are not native to Owl Acres, though. They’ve been introduced as forage species for cattle, or lawn species for the yard. Most of the […]

It started breaking up around 780 million years ago, but the core of it stayed together and in time became the Laurentian Craton. This mass of rock would eventually form the foundation of the continent […]

Owl Acres stands on a specific if tiny place on the earth’s surface. It can be measured in longitude, latitude and altitude coordinates and thus pinpointed precisely. With the help of satellites, my phone can give me those exact coordinates, and they would be unique to this very spot on the entire globe. But Owl […]

When we were kids, playing in the mud, we used to dream about digging all the way to China. Wouldn’t that be fun? To escape through a tunnel into a completely different place? We didn’t realize, of course, that we’d end up in the Indian Ocean instead of among the Celestials. Our excavations never got […]
