PEN-Y-GHENT 01A - Pen-y-ghent

Penyghent near Horton in Ribblesdale in the Yorkshire Dales.
Largely composed of Great Scar Limestone, Penyghent was formed about 330 million years ago when the area lay beneath a warm shallow sea. The limestone was deposited in layers as tiny sea creatures died and became compacted on the sea bed. Over millions of years other deposits created the later Yoredale Strata of alternating layers of limestone, sandstones and shales above the Great Scar Limestone. The summit rock of Penyghent is Millstone Grit (interbedded coarse sandstone and shale). There is black shale in the path near the summit..
