Thanks to Dan Soper for publishing this one on the Pembs Geology Facebook page -- a "stack" of clifftop till at Penycwm, north of Newgale. It's gradually being whittled away by erosion.
The boulders at the base of the stack appear to rest on brecciated bedrock / slope deposits. I'm not sure of the significance of the change of colour between the lower part of the till stack and the upper layer -- I need to get over there to have a look......
Almost certainly this till is of Late Devensian age.
