Human excrement has been found by a team of avalanche risk forecasters on a footpath leading to one of Scotland's beauty spots, Creag Meagaidh.
The BBC reports that the waste and rolled up tissue were discovered in Coire Ardair near Creag Meagaidh, a 20-minute walk away from a public toilet.
Sportscotland Avalanche information Service's local forecasters said the area was almost pristine.
Part of a national nature reserve, Creag Meagaidh lies between Inverness and Fort William.
One of the avalanche information service's forecasters said Scottish Natural Heritage built a toilet for visitors in the area two years ago.
Speaking to the BBC, he said: 'As toilets go it's a good one. It's clean, well-lit, has copious amounts of bog roll. It's even got its own heating system.
"You can't miss this particular public convenience because it's exactly as stated: very public and very convenient.
"Almost all visiting Creag Meagaidh will have passed right by it. It's difficult to miss, so please use it."
Five years ago a 'poo chute' was installed for Cairngorms Ranger Service to tackle problems with human waste being left on their mountain range.
Visitors are given bags and light, rigid bottles with a screw top from the ranger base free of charge.
Walkers and climbers then deposit the bags down the chute and place the bottles in a sterilization barrel.
