==== 2 Gipsy Point: slump ====
A walk of some 300 m in a WSW direction, keeping the old tank to the left and crossing a ruined wall, brings the visitor to the cliff top at Gipsy Point (NX 685 436). A new military earthwork lies just to the west. The slump, which lies within the B Member of the Gipsy Point Unit, is well seen from the cliff top. It is some 30 m thick and lies within a channel-fill sequence consisting of chaotic and disordered thin-bedded sandstones. The sequence is vertical and youngs NW; above and below the slump the beds are undisturbed. One prominent horseshoe-shaped sedimentary fold within the slump sequence is particularly evident from this vantage point. It is clear that the sediment forming the slump must have slid down the process, but remaining cohesive.

It is possible, with care, to descend to the coast from here, to examine the slump more closely. The erosive base of the slump (SE side) can be seen cutting into the underlying beds, forming fossilized channels with flute casts; in some places rip-up clasts can be seen in the mudstone. The whole sequence has been folded by a large anticline–syncline pair which traverses part of the section and is clearly seen as a large box-fold on the vertical face near the point of descent from the cliff top.
