All,
I was walking in the far north, between Kildonan and the headwaters of the River Thurso. We covered a large distance over featureless peat bog.
However, there were what looked like some sinkholes in the peat, and a few of them had actual cave passage in the peat! I didn't pursue them as I didn't want to get wet grovelling around in the wet gravel.
As far as I can see, there is no limestone.
It looks like the water has eroded a number of passages at the base of the peat, which can take quite a flow of water.
Is this known about?
Chris.
