Schiehallion Richard Murray: that so well defines the rocks south west of Tummel Loch, BGS have a map of the mountain geology which I shall be inclined to pin on the wall for reference and a good picture with this, or go across the Trinafour route again and down Tummel edge instead of Struan, or up from the east and take one of my own, but that is a beautiful image and clear cut. Mike. Loch Errochty in storms is very good also, good long walk through forest and back down around the road hydroelectric pipe (hidden in the trees on lower slope) route, with soil slips and small waterfall cascades, you just need to have a head for heights and sure footing on the massive deer fence stile. Great trees and ground cover side streams walk, so all that, Trinafour and Schiehallion, can be completed in a couple of days. A little alike Tryfan and Llanberis Pass, or the basin lakes Plas y' Brenin, Capel Curig and the Llyn Crafnant walk Martin Spray set up for the students in 1974, do-able in a day as they say in DIYSOS, although they take a week and have twenty plasterers and several musicians and designers and chutney festivals and giant dinners and cakes ..., tough life Geology, beef jerky solid bread rolls, cold squash, dry cereal bars, Kendall Mint cake, or perhaps the fabulous Butternut potato soup in the elevated forest cafe off the A9, but less of the asthmatic dust and giant spiders down the neck as in Wildlife programmes. You can find some peacock and peahen at Urrard and also Trefriw, as horse jumping at Llanrwst opposite the river crossing, but do walk, or you will not meet the Capercaillie and domestic birds at close quarters, or even Quarter Horse training and the fish and chip evening snack at Betws-y-Coed, or Brecon sitting in the impending rain fresh air. A good place to go even if Scottish Mountaineers can walk Tulach Hill in 1.5 hours from the Rail as an evening stroll before dinner! depressing for the rest of us mortals. Perhaps they avoided the stream jungle wading and slippery rock planes?
http://shop.bgs.ac.uk/Bookshop/product.cfm?p_id=S055WSFyou can get £80 versions of Blair Atholl and also Pitlochry sheet and Newtonmoor, or just use other sources of secondhand and leftover prints still new of reports, the region seems of rare and primary quality demand, there is a BGS
www.bgs.ac.uk/downloads/start.cfm?id=1884minerals which has a brief outline of the geology, or use the Grampians report Stephenson and Gould, Colin Prior's books give good insights into the rocks due to his preference for high difficult terrain at times of day Capercaillie are just waking. Geology can be costly, or you can read and put it together yourself and select sites, which if applied to other work is good fun as well as productive, just a little wet cold and windy. Thanks for the picture I have a large reference list of works by experts on website accessible if you wish to get serious "headache" as our neighbour's daughter used to say, trying to make a picture in your mind of the region subsurface and present events.
