“Triassic bunter, that’s yer problem. All those little round stones were once at the bottom of a very large, very fast prehistoric river in northern France or southern Germany. They found their way to their current slippy location sometime in the last ice age.”
Triassic bunter beds were laid down in the Triassic period which wasn’t the last ice ige. Although Shropshire and Cheshire do have glacial deposits form the last ice age circa 10-20k years ago.
Yes, they were slippy last week but this just makes the Dog a different challenge.
