There is nothing to see from the ground, no earthwork, no upstanding feature, nothing that would catch the eye of a passing farmer or walker. What is known about it comes almost entirely from the air.

The site was identified during the Bruff aerial photographic survey in 1986, recorded as a circular cropmark and catalogued as reference Bruff 131, AP 5/2077. Cropmarks form when buried features, the ditches or banks of an ancient monument, affect how vegetation grows above them; in dry summers, differences in soil depth and moisture cause crops or grass to green up or wither in patterns that mirror whatever lies beneath. The circular outline visible in the 1986 photograph is consistent with a barrow, a prehistoric burial mound, though the classification remains tentative. The site does not appear on Ordnance Survey Ireland historic maps, which suggests it was either already levelled before systematic mapping began or was never prominent enough to record. It sits in pasture roughly twenty metres north of the townland boundary with Kilfrush, a quiet administrative line that now marks the edge of what might be a very old place indeed. Later imagery, including Digital Globe orthoimages from 2011 to 2013 and Google Earth photographs, shows no surface remains at all.

Access to the immediate site is not publicly documented, and as it lies on private farmland there is no formal visitor infrastructure. For those with an interest in the archaeology of the Bruff area more broadly, the 1986 aerial survey that brought this site to light was part of a wider programme of landscape recording that identified numerous features across south County Limerick invisible at ground level. The best time to observe cropmarks of this kind, if aerial photography is available, is during dry spells in late summer when soil moisture differences are most pronounced. On the ground at Coolalough, there is genuinely nothing to see, which is itself a quietly unsettling fact about the nature of what might be buried here.
