Scar' (bed 496) and East Scar (bed 494) opposite the town, and Cowling Scar (bed 474, Double Band) farther out to sea near the bottom edge of the map. The relatively soft beds of the Pyritous Shales around Ground Wyke are the wettest and lowest (relative to sea level) exposed part of the foreshore in the bay, where there is now little or poor rock exposure owing the seaweed, barnacle and mussel bed cover. Map 3 (Fig. 8) shows an interesting entity of outcrops around the mouth of Mill Beck, the cliffs that make up 'The Nab'. and the major rock scars on the foreshore to the east. There are three prominent scars here - Low Scar, Middle Scar and High Scar, being the hard, calcified silty shales of beds 447, 449 and 455 respectively. Also notable on this map are Tinkler's Stone and Strickland's Dumps, north of the mouth of Stoupe Beck, and both are named on the larger scale Ordnance Survey maps. Tinkler's Stone lies on bed 462 and is a boulder of very hard grey-brown massive limestone, of undeter- mined origin, but not derived from the Lower Lias. Strickland's Dumps are small, but relatively deep, excavated pools in the dip slope of beds and The area around Bay Mill and The Nab is shown on a larger scale in Fig. 9. High tides penetrate well into the mouth of Mill Beck between The Nab and the road on the south side of the beck, and sometimes large masses of dead algae partly block or divert the outflow of Mill Beck. However, when the mouth "Scar' is a term frequently used in descriptions of Yorkshire coast geology for rock outcrops on the foreshore, which are usually below (but may sometimes be above) th
