A Sunday Mystery Photo...


Here's a little mystery to start off your Sunday morning web browsing. What's going on here? Clues: Trees and sage provide scale, and it's in British Columbia. No shame in wrong guesses!

Hexagonal cracking? periglacial?

Bison wallows?

Perhaps periglacial patterned ground... Or perhaps man-made in some way.
The picture doesn't match karst topography that I've seen. Nor does it look like the bison wallows a quick Google search turned up.
So what's the answer, Garry?

Looks like ground squirrels or maybe prarie dog colonies but I think BC is too far north for dogs.

Jane Strong said...

"periglacial " feature in area of discontinuous permafrost maybe? caused by alternate freezing and thawing sorting the rocks
