In order to explore the topography of Western Strathearn we will divide the Strath down the middle and with a broad brush provide the principal names of the mountains, hills, small glens, and streams and burns which have been ascribed by man to its geographic features. We will identify some Munroes (above 1000 metres), Corbetts (800 to 1000 metres), Grahams (700 to 850 metres), Donalds (similar to Grahams but with additional dimensions). Others, yet again, are also categorized as Marilyns. Marilyns do not necessarily have to have height rather than mass with the final 150 metres being more of a climb than a hill walk.
To the south and east, rugged Highland Grahams (610-760m) and Corbetts (761-914m) with the two great Munroes (915m+), Stuc a’Chroin (972m) (pinnacle of the ploughshare), which shoulders Beinn Each (811m) (mountain of the horse) in Strathyre and Ben Vorlich (985m), are clearly seen. From the loch side and following the uphill course of the Burn of Ample from the recently restored Edinample Castle (originally built by “Mad” Colin Campbell of the Cowl in 1603 - of more later) up through and beyond the Falls of Edinample (oadann ambuill - face of the vat referring to the shape of the Falls) into Glen Ample but below the summit of Ben Vorlich, we direct our footsteps eastwards with Loch Earn in view on our left from all heights. Highland heather, bog, craggy knolls and layers of lightly covered soil over solid rock, and sheep and deer paths crossing numerous burns, as well as wee hidden glens, are our lot for the next ten miles or so. If we are lucky in autumn we will see herds of deer in the distance, but sadly never get close to them.
Passing Coire’ Baile a’ Mhaoir (wood of the farm of the maor (officer of justice - it could also mean steward or warden which may have relevance to the Stewarts of Ardvorlich) we reach a tributary to the Ample Burn called Allt a’ Coire Mheobhith (burn of the dell of lively life) which leads us towards Coire Mheobhith which is the starting-off point for our skyline walk. Ahead we pass between Beinn Our (the dun coloured hill) (730m) and Sron Mhor (670m) (great slope or promontory). These are delightful stopping-off points for those climbing Ben Vorlich (the hill of the great hollow) lying higher to the south-west. Progressing eastwards over boggy ground we reach Coire Buidhe (yellow corrie). Here a natural spring, Allt a’Choire Bhuidhe (burn of the yellow corrie), gurgles, forms and flows into the Ardvorlich Burn which in turn passes through Glen Vorlich. This is the hereditary estate of the Stewarts of Ardvorlich, (little bay on the loch), and thence into the Loch itself. The Ardvorlich Burn sources itself at a small loch called Lochan na Mna (little loch of the woman) which is nestled to the south-east below Creagan an Lochain (crag of the little loch). There is an interesting tale attached to it which will be seen in the chapter on the Stewarts.
Below us Eildrich (556m) (abounding in hinds) and An Dunan (489m) overlook the Balimeanach (middle farm) Burn which sources itself through the boggy marsh flanked in the east by Beinn Bhan (640m) (white hill) and the Black Craig (692m) and its cluster of bogs and hillocks called Druim Chonnaidh (firewood ridge). Below lies Fin Glen and the effervescent Allt Shuas (Wester burn) parallelled by its sister stream, Allt Shios (Easter burn), whose source lies in the boggy land of Meall Reamhar (630m) (round lump of a hill). At Meall Reamhar we note the sources of the streams called Allt Tobar Sneachda (burn of the snow well), a tributary of Allt Shrath a’Ghlinne (burn of the strath of the glen) flowing south-eastwards between Creag na h-iolaire (650m) (eagle’s crag) and Meall nan Saighdearan (650m) (hill of the soldier) to the north-east. It, and its parallel sister, Allt nan Saighdearan (burn of the soldier), are tributaries of the Water of Ruchill which we will meet at Comrie.
Moving on to Bealach Ruadh (608m) (the red pass) we round towards Beinn Fuath (661) (mountain of the spectre) and Am Bioran (613m) (the sharp or pointed one) and Bioran Beag (the little sharp one) circling in the lower reaches, Creagan na Monteich (crag of the peat moss) and its supports of Dun an Aon Duine (the fort of one individual) and Fhuar Chois (cold hollow) and, within the envelope, Glen Fhuarchois (glen of the cold hollow) with its stream, Allt Fhuarchois (burn of the cold hollow), changing its name lower down to Allt na Galanaich (burn full of branches). Here it enters Loch Earn at Ardrostan (height of Drostan - a Celtic saint). Flanking this burn are the knolls of Sron Mhor Mhic Laurinn (great slope of McLaren) and higher Mhic Laurainn (McLaren) and another stream coming off the hillside called Allt Fhiantagan (burn of the black heathberry) which in turn is flanked by Cnoc a Mhadaih (173m) (hillock of the wild dog) overlooking St. Fillans, and the crannog known as Neish Island.
Returning to the heights of Beinn Fuath below, and to the south-east, lies Gleann Ghoinean (glen of the withered grass) with its stream, Allt Ghoinean (burn of the withered grass) later changing its name to Bealach an t-Sagairt (pass of the priest) which joins the River Earn to the east at that ancient place, Dundurn (Dunduirn - fort of the fist). Here the Strath narrows to about three miles in width and staying on our course we round into the massif known as the Aberuchill Mountains (obair-ruchaill - confluence of the Ruchill) (with the Earn at Comrie) with the mountains consisting of Mhor Bheinn (640m), Bioran Dalchonzie (468m) and closer to it, Beinn Bhearnach (604m) (mountain abounding in clefts) and Ben Halton (621m) (Beinn challtuin - hazel mountain). At our feet lies the broad, open flatland of Lower Strathearn with the Village of Comrie (approximately 600m) below.
