Dumbarton Rock safety report


The recent geo-engineering survey  at Dumbarton Rock, commissioned by Historic Scotland, on the NW face (main climbing area above the boulders) has thankfully found no major instability and we hope that responsible climbing can continue as normal at Dumbarton. The report summarises the situation thus:

'The principal potential hazard noted at the NW inspection area is unstable blocks becoming detached 
from the face and falling onto areas below.  It has been established through visual inspection of the area that the rock mass is generally tight, and although there are a number of well developed joint sets, there is little evidence that the intersection geometry is creating significant viable or active rockfall events. This is not say that rockfall will not occur, as from time to time material will dislodge from the face due to natural processes, but these are likely to be relatively infrequent and are impacting areas with only transient pedestrian traffic. Given these criteria – infrequent rockfall events and infrequent transient pedestrian traffic - It is considered that the risks to members of the public, both below the castle and within the walls of the Duke of York’s Battery area, may be managed through regular inspection and monitoring. The risk of instability and damage to the castle infrastructure may also be managed in the same manner. The installation of rockfall warning signs at the base of the slope to warn the public of the risks would be considered appropriate.'

The Lost Township of Grulin on Eigg

‘The Stony Place’ as it translates, the archaeological notes on the RCAHMS database for Eigg, state baldly the lost humanity of Grulin as early as an 1880 OS survey map: ‘…eighteen unroofed buildings, six enclosures and a field-system’. Now a scheduled monument and memorialised as a ‘depopulated settlement’, though it is not obvious if the verb is passive or aggressive, Grulin Uachdrach (Grulin Upper) is, like Hallaig on Raasay, a place of violent silence and resonance. Who lived here and why was the site abandoned? If it were not in Scotland, suspicions might fall to the climate, remoteness and apparent unsustainability of the stony place, a rabble of large rocks under the steep slopes of An Sgurr, but the carefully constructed walls tell us it was once a thriving township – the kilns, folds and blackhouse walls integrated with the giant boulders such as Clach Hosdail. In 1853 the whole of the village of Grulin, both upper and lower, housed fourteen families who were forced to l...

Timeline Walks of Scotland #Hallaig to Screapadal on Raasay

'Tha tìm, am fiadh, an coille Hallaig ...' Hallaig - the lost village of Raasay - is a powerful place. Arguably, it has become a shibboleth for the soul of Gaelic culture. To visit it, to just be there momentarily and feel the resonance of the place, is to know the fragility of place and home, of how kinship can be shattered and how loss can invade a land. Aptly, Hallaig is now a site of pilgrimage for those who value the universal lessons of history.  There are t errible reasons for the loss of Hallaig. Its silent mouths of abandoned shielings, the dumb sheep meandering amongst the ruins, whisper with Sorley MacLean's poetry. The place misses the sounds of day-to-day community, and all around the woods and burns and slopes this tough but rich landscape once made this a hardy paradise under the eastern cliffs of Raasay. Facing east to the dawn and overlooking the peninsula of Applecross and the berry-dark depths of the Inner Sound, the walk to Hallaig leads quietly...

Scotland's Iconic Mountains #Broad Law

BROAD LAW The rolling hills east of the modern motorway of the M74 hold much more character and history than they appear from the west, where they are now flanked by forestries of spruce and wind-farms. In medieval times this was a Scottish royal hunting ground – the ‘Ettrick Forest’.  Further east towards the Tweed valley, there are echoes of a deeper Scottish history in the border towns of Hawick, Selkirk, Galashiels, Peebles and Kelso, all on the banks of the historic River Tweed and famous for their medieval forts and abbeys.  Looking west from Broad Law to the monoculture forestry and wind-farms of 21st C Scotland This range of hills, along with the northern flanks of the Cheviot hills, marks the geographical transition to the once-contested border with Northumberland, with its high pass over Carter Bar on the A68. The more useful sense of boundaries are suggested not by the roads but by the watersheds: to the north the waters drain into the River Cly...
