Ripple beds, Wren's Nest
What looks at first like a concrete wall is the top of the Nodular Limestone Member of the Much Wenlock Limestone Formation. The rock face has been exposed by quarrying of the overlaying (younger) Upper Quarried Limestone Member in the past. The dip is too steep for soil to form on the surface. However, the exposure isn't totally flat: a wavy pattern has emerged due to wave action when these rocks were deposited - this is known as a ripple bed. The Nodular Limestone Member consists of thicker limestone layers interbedded with thinner sandstone, which explains the spalling off of large sheets as can be seen on the right.
