Mountaineers and hillwalkers are being urged to steer clear of a remote shelter while restoration work takes place.
The Hutchison Memorial Hut lies in Coire Etchachan in the shadow of Sgurr an Lochan Uaine in the Cairngorms, but needs major building and maintenance work.
The Mountain Bothies Association, which looks after the shelter, said work is likely to last three weeks and will start on Friday 31 August.
During that time, the bothy will not be available for use and outdoor enthusiasts will need to camp or find alternative shelter in the area.
A plaque on the bothy says the Coire Etchachan shelter was erected in 1954 in grateful memory of Arthur Gilbertson Hutchison who died in 1949.
Dr Hutchison of Aberdeen was killed in a climbing accident in Pembrokeshire and the commemorative bothy was built with permission from the trustees of the late Duke of Fife.
Local climbing clubs and other enthusiasts helped carry building materials to the site 700m (2,297ft) up in the Cairngorms for an Aberdeen firm to carry out the construction.
The Mountain Bothies Association cares for about 100 rudimentary shelters in remote parts of the UK, most of which are in Scotland. Its maintenance work is carried out by volunteers.
