This rock lies within the Wilton International Site, so cannot be viewed by the public.

The plaque says everything you need to know :-

This 3.8 ton piece of calcareous limestone (containing shells) was transported by glaciers and deposited on the Wilton site between 70,000 and 13,000 years ago.

Mick Garrett took this shot 14 years ago.

Although the rock hasn’t changed, the surroundings have.
