The site sits on a gently south-east facing slope overlooking Minard, its roughly circular outline measuring twenty-three metres across internally, and its entrance gap of three metres opening towards the south-east in the classic manner of Irish raths.

A rath is an earthen ringfort, the kind of enclosed farmstead that was built and occupied across Ireland roughly between the fifth and twelfth centuries. What makes the example at Log Na Gcapall worth pausing over is the specificity of its surviving earthworks. The fosse, a defensive ditch encircling the inner bank, reaches four metres in width and drops two metres below the surrounding ground level on the outside, and three and a half metres below the crest of the bank itself. That is a considerable depth, suggesting the enclosure was built with some seriousness of purpose. An outer bank also survives along the south-east sector, though only to about 0.75 metres in height. The fosse itself is present only around the south-western half of the site, which is not unusual; earthworks of this kind were often asymmetrical depending on the terrain and the perceived direction of threat. Details of the site's dimensions and layout were recorded by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a foundational catalogue of the area's field monuments.

The interior is densely overgrown, which is both a hindrance and, in a way, a form of preservation. Heaps of stone are visible beneath the vegetation, and a possible house site has previously been recorded within the enclosure, hinting at the domestic life that once played out inside these banks. Raths of this kind were typically the homes of farming families, their banks and ditches less about military defence than about marking status, enclosing livestock, and defining a household's territory within the landscape.
