Shap granite erratic near Redcar

Glacial erratic, Shap Granite, found on beach between Marske & Redcar (at NZ 62912 23492) after rough seas (Jan. 2010) had removed sand. Characteristic rectangular feldspar phenocrysts are visible. GPS is 16cm long.

I found this photo on the web of a well-known erratic boulder -- purportedly from Shap -- on the beach near Redcar.  It looks very different from the pink erratics at Flat Holm and Saunton........  and this one has of course travelled across the Pennines from near the west coast to its resting place on the east coast.  That's no great surprise -- it fits with what we know about ice movements in the UK.
