Otter Cove

The cliffs at Otter Cove are formed mainly of mudstones belonging to the Aylesbeare Mudstone Group, interbedded with red sandstones.^[1] These rocks date from the Triassic period, around 245 million years ago.^[2] Their distinctive red coloration reflects deposition in an arid desert environment.^[3]

In the corner of Littleham Cove, there is a marked fault, producing a distinct change in the character of the cliffs.^[1] South of this fault, at Otter Cove, the succession is dominated by fluvial sandstones that include beds with coarser, dark, subangular grains, approaching the texture of a fine-grained fluvial breccia.^[2][4]

On the eastern side of Straight Point, the cliffs expose sandstones of the Exmouth Formation.^[1] Access to this area is restricted to low tide from Littleham Cove, as noted in the official site designation.^[4]
