Freshwater Algae from Loch Skeen, 26th May 2002
Loch Skeen lies in a glacial hanging valley in the Scottish Borders area: the Tail Burn which drains it cascades into the Moffat Water, forming a waterfall called the Grey Mare's Tail. The area is popular with tourists, and a steep but well-constructed path leads up the side of the waterfall to the loch. |
