An item in a past letters page mentioned the boulder in Sutton Park that was brought down in the last Ice Age.

As far as I know there are three such boulders. One is mainly buried just off Mill Lane in Sutton, and the third is in the Friends Garden off Shaw Street. Whether there are any more in the present fifty square miles of St. Helens, I don’t know.

They would make very distinctive boundary markers in Anglo Saxon times and may have names in ancient wills and other documents.

One caller remembers the one in Sutton Park surrounded by railings and a plaque which told readers the boulder had come down in the Ice Age from the Lake District, that it had been polished on two sides by the action of being dragged by the ice, and that it weighed one and three quarter tons.
