It does not appear on any edition, old or new, which is itself a small curiosity, given that holy wells were mapped with reasonable diligence across much of Ireland during the nineteenth century. What remains on the ground today is even less forthcoming: a waterlogged depression, nothing more. The dressed stone steps that are believed to have descended from ground level down to the water source have vanished entirely, leaving only the boggy hollow where they once led.

Holy wells in Ireland were typically sites of pattern days, communal gatherings held on a saint's feast day that combined religious devotion with rounds, prescribed circuits walked or performed on the knees around the well, along with offerings and a good deal of socialising. At Sliss, that tradition is now beyond living memory. Fr O'Keeffe of Asdee, recorded in C. Toal's North Kerry Archaeological Survey of 1995, confirmed that no patterns or visitations had been held there within any memory he could draw on, though local tradition preserved the knowledge that such observances did once take place. The well was remembered, even as the practice around it had faded, and even as the stonework that gave it form had disappeared into the ground.
