That absence is itself a curiosity. The mound was never recorded in the layers of cartographic documentation that catalogued so much of the Irish landscape over the nineteenth and twentieth centuries, which raises the question of whether it was simply overlooked or whether its nature was never quite understood by those who passed it.

The site came to official attention in 1999, when archaeologist Celie O'Rahilly was walking the proposed route of an ESB power line and noticed the feature, logging it as Site 17. Her description noted that the mound is orientated roughly WNW to ESE and that at ground level on its south-western side there is a recess cut into the fabric of the mound, lined with two parallel drystone walls set approximately two metres apart. Drystone construction, that is, stonework built without mortar, is found across a wide range of Irish monument types and periods, so the walls alone do not pin down the mound's origin or function. What is more telling is the material the mound itself is made of: a dark, gritty sand that contrasts noticeably with the surrounding clay subsoil, suggesting the material was deliberately deposited here rather than formed naturally. What purpose it served, and when, remains unresolved. The site was still visible as a scrub-covered mound in Digital Globe aerial photography taken between 2011 and 2013, and in Google Earth imagery from March 2012.

The mound sits close to the confluence of the small stream with the River Shannon, in an area of estuary edge that is not heavily trafficked. Because it is not marked on historic maps and carries no formal monument signage, finding it requires some patience with satellite imagery and a willingness to navigate across what is likely soft, low-lying ground near the water. The hawthorn canopy that covers it will be most penetrable outside the growing season, when the scrub is less dense, and that is also when the recessed drystone feature on the south-western face is easier to examine at ground level. Anyone interested in the site should be aware that its character, a deliberately constructed earthwork of uncertain date and function in an estuary landscape, may reward careful observation more than any single definitive answer.
