Location and geology
The site lies in the Cotswold Area of Outstanding Natural Beauty and is considered one of the best exposures of the Hampen Marly Formation of the Middle Jurassic period. The exposures in the cutting show the complete section from the top of the Lower Fuller's Earth Clay to the middle of the White Limestone Formation. This is a prime research site for understanding the variations in rocks of this age between the Cotswold shelf and the Wessex area.
