Those keen on some winter climbing in the Scottish mountains should make sure they know the shape of the hill they are on to aid flexibility, an expert has advised.
Writing for Summit - the British Mountaineering Council's members' magazine - winter climber Dave MacLeod said that those undertaking a climb may benefit from good contingency planning as their original route up might become impossible.
This could happen due to changes in the weather, avalanche risks or alterations to the route conditions, he noted.
"Knowing the layout of the mountain means that you can keep all the options in your head from the moment that you step out in the morning," Mr MacLeod stated.
Those stocking up on some climbing gear
before taking on such challenges may wish to buy Ordnance Survey Maps
of the mountains they are visiting so they can carry out such study.
Alan Hinkes, the first Briton to successfully climb all 14 of the world's mountains over 8,000 metres in height, has described Scotland as his favourite place to go winter climbing.
