Caption: Trough cross-bedding at Rookery Lane, Haywards Heath, Sussex.
Description: Looking west at Rookery Lane, Haywards Heath. Trough cross-bedding ('festoon bedding') in Cuckfield Stone. In the area between Danehill and Haywards Heath the Cuckfield Stone occupies a channel which cuts out much of the Lower Grinstead Clay. Within this channel the sandstones are commonly 'festoon bedded' and it seems likely that this type of bedding is directly related to channel deposits, both features being formed by a shallow, braided stream. As elsewhere in the Cuckfield Stone, the sandstones characteristically weather to an attractive dark to honey brown, an indication that they were in part originally calcareous. The Cuckfield Stone is a lenticular body of fine-grained sandstone that divides the Cretaceous Grinstead Clay into lower and upper members. The Grinstead Clay is a shallow lake deposit with a beach barrier bar, meander belt of distributary channels adjacent to a levee with spillover lobes.
