The peat here is not merely deep; it is effectively a time capsule, preserving the ground surface of an earlier agricultural landscape that was eventually overwhelmed and buried. What makes the site at Glan Lough quietly arresting is precisely this incompleteness: the walls do not form a legible pattern that can be mapped and understood at a glance. They surface at intervals, suggest something larger, and then disappear again beneath the bog.

Glan Lough sits at the southern end of a steep glaciated valley on the northern flank of the Dingle Peninsula's central mountain ridge, hemmed in by Knockbeg at 381 metres to the east and Knocknakilton at 426 metres to the west. The exposed portions of the buried field system lie directly north of the lake, within an area of roughly 300 by 400 metres. Six separate walls have been identified, roughly straight and varying from a few metres to 75 metres in length, though the full extent of the system could not be established. Most survive only as collapsed spreads of stone, one to three metres wide, but in places low upright stones remain standing where they were originally set, and one short section retains three to four courses of dry-stone masonry intact. Dry-stone construction, that is, walling built without mortar, was the standard technique for field boundaries and enclosures across early Irish landscapes. Nearby, about 300 metres to the west, there is also an isolated souterrain, an underground stone-lined passage or chamber of the kind typically associated with early medieval settlement and sometimes used for storage or refuge. The two features together hint at a period of more intensive human activity in this valley than the present emptiness of the moorland would suggest.

The overall layout of the field system remains unknown. The peat conceals far more than it reveals, and the relationship between the walls, the souterrain, and the wider valley landscape is still unclear. What has come to light is fragmentary, almost accidental, uncovered not by excavation but by the slow practical work of cutting turf.
