Chaidh Rathad-iarainn Inbhir Pheofharain agus an Eilein Sgitheanaich fhosgladh ann an 1870 ach cha deach e na b' fhaide na Port an t-Sròim air Loch Carrann. Bhiodh seachd bliadhna fichead eile ann mus ruigeadh e stad-crìche Chaol Loch Aillse. San earrainn seo, cluinnear Iain Tòmas (1914-1982), fear dhe na eachdraichean b' ainmeile ann am Breatainn, agus e a' deanamh coimeas eadar na loidhne agus an fheadhainn a gheibhear an sgìrean san Eilbheis. Chaidh a chlàradh air bòrd trèana shònraichte air turas gu Caol Loch Aillse ann an 1973.

Just near to Raven's Rock summit we have the junction of two rock types; to the west, and including Raven's Rock summit, we have the old metamorphosed rocks which are called by the geologists, the Moine Sequence. To the east of this line, a few mile, a few - a mile or so from Raven's Rock summit we have the outcrop of the Devonian Old Red Sandstone; the middle sequence of this particular geological succession. So the type of stone which we have at Raven's Rock summit, are complex rocks of a metamorphic type called the Moine Rocks. They've been subjected to repeated earth movements. There have been, in fact, probably four earth movements, four sequences of twisting and folding the rocks in a very complicated way. The pressures which folded the rocks have come from several directions - not always the same direction - and the oldest of these has been dated recently by radiometric dating techniques to be something in the order of 750 million years ago. These rocks originally were rocks which were sediments which were laid down in fairly deep water. At the same time, the Torridonian sandstones, which we were travelling over in the Duirinish, Drumbuie, Plockton, Strome Ferry area, they were laid down approximately the same time in much shallower water
