The caves are situated on the west side of Keshcorran Hill (part of the Bricklieve Mountains) and consist of sixteen simple chambers, some interconnecting.

[3] The sixteen interconnecting caves of white cherty limestone are found at the base of a line of low cliffs, on the western slope of the hill.

Quartz crystals are abundant, and glacial boulder-beds can be found at the mouth of some of the caves, showing that Keshcorran was at one time buried beneath an ice sheet.

Another recovery of note was that of several fossilised frog bones found in the lowest stratum, which disproved a common belief that the species had only been introduced in 1699.

[5] Finally, the excavations found evidence of occasional human habitation going as far back as the Neolithic, with more regular occupation being identified from the 10th century onward.

[5] Further explorations took place in 1929 and 1930, and these led to the recovery of more bones of lemming, reindeer, mouse, pig, hare, horse, frog, rabbit, sheep, fox, stoat, bear, dog, ox, badger and rat.
