Thank you to Rachel for sending this postcard from Aberfoyle in the Trossachs.
The Trossachs is an area of glens and braes (valleys and hills) in central Scotland. One of the valleys holds Loch Lomond, a freshwater ribbon lake formed after glacial erosion at the end of the last ice age gouged the pre-existing v-shaped valley into an over-deepened trough. That happened between 10 000 and 20 000 years ago, which is practically, just moments ago in geological terms.
Now the area is a national park and home many species such as black grouse, ptarmigan, pine martens, mountain hares and golden eagles.
