The cliffs from Trimingham to Sidestrand are some of the most spectacular glacial formations along the northern Norfolk coast. These tall, rapidly eroding cliffs here display an array of various colours from the sands, tills and clays. Fossils are mostly Jurassic and Cretaceous erratics.

At Crimplesham, Kimmeridge Clay and Oxford Clay are exposed. Within the Oxford Clay are large nodules, which contain ammonites, brachiopods and bivalves. The quarry is slowly being backfilled, so collecting is becoming more limited. Jurassic, Working Quarry, Rating: ♦♦♦
