|Location||Red Quar, Chewton Mendip|
|Geology||Dolomitic Conglomerate and Marl|
It is unusual for a cave on the Mendip Hills in that it is not in limestone but instead in Dolomitic Conglomerate and Marl. The main part of the cave was first entered in 1992, although Red Quar Swallet had been dug in the 1930s and the entrance shaft is now a concrete pipe. .
It takes its name from the Attborough field in which the entrance is situated. Red Quar Swallet comes from the small scale quarrying of red Triassic conglomerate.
