The site is a fulacht fia, a type of prehistoric cooking place typically consisting of a trough filled with water and heated by dropping fire-cracked stones into it; the discarded stones accumulate over time into a distinctive horseshoe-shaped mound. Here, however, the original oval shape has been so thoroughly altered by centuries of ploughing that what remains is largely a broad, flat scatter of burnt stone rather than any recognisable mound form.

The spread is considerable. Measured east to west, it extends to 53 metres, while the two halves divided by the fieldbank run to 38.5 metres and 47.6 metres respectively along the NNE-SSW axis. A small stream to the south-east drains into Ballylongford creek, which is exactly where you would expect to find a site of this kind; fulachtaí fia are almost always positioned close to a reliable water source, and the low-lying, well-watered land of north Kerry is particularly dense with them. The proximity to Ballylongford creek suggests the stream has been in use here, in one way or another, for a very long time.
