Glacial striations

You never forget a good teacher, do you? Mr Aldred was one of my geography teachers (the other being Mr Boocock). Mr Aldred was one you never forget. I can still hear him speaking about glacial striations in our physical geography lessons as clear as I can hear him saying limestone pavement. It’s as if he’s in the room with his balding head, speech impediment and wide lapelled suit jacket.

Here are some glacial striations on Westray. They are deep grooves in the bedrock carved thousands of years ago by boulders trapped under thousands of tonnes of ice as it melted and retreated back towards the North Pole at the end of the last Ice Age.

They’ll still be here thousands of years after we have gone.
