The next stop on our trip around the Trotternish peninsula of Skye was the Diatomite works at Inver Tote. Diatomite (known locally as Cailc) was discovered at Loch Cuithir in 1886. By 1889 the Skye Diatomite Company was extracting Diatomite from the loch and transporting it via railway to drying sheds at Inver Tote. The remains of the sheds can still be seen today although the railway has long since gone.
Wikipedia page is quite informative.
