There has been confusion between this site and site 2378. Site 2379 seems to be on a grassy area. More confusingly, site 2378 may have not been seen when 2377 - 2379 were originally found. This had a grid reference of 30T 451287 4796829 (Datum: ETRS89).
At Easter 2017, it was described as a very small 2m deep rift with no draught.
