Sgurr Coire Coinnichean rises steeply 2612 feet above the Inverie woodland. A ravine on the south-western side splits the bedrock beneath the serrated profile of the ridged peak is – Sloch’d a Bogha ("Pit of the Bow(uh)"; “Sloch” describes this geological feature as a hollow, pit, or cavity. Boga/bogi a term borrowed by Irish and Scottish Gaelic from Old Norse, translates as “sunken rock”. Looking north from the distance of the Inverie river, this mountain’s deep faultline is a dark shadow in bright sunlight.
Water collects at the head of a stream of the same name before running below the ravine; on the first Ordnance Survey map of 1873-76 its name changes to Allt Doilleirochte (Obscured burn). Where it runs off the hillside, on the boundary with the Kilchoan estate, the stream rises to the level of the woodland path after heavy rainfall. In drier seasons, water flows over boulders and slabs of bedrock, brought down in flood, before spreading over the beach by Inverie House. Between tides it trickles out to sea across sand, gravel and muddy silt, returning elements of land and life to the wind and waves. The Obscured burn brings to mind the Sliochd Alein’a Alein, the progeny of Allan, whose power rose and fell before sinking from sight.
