The frost tightened it’s grip as evening fell, whipped up from the chill Arctic wind in from the sea and south over the desolate winter landscape. It plunged down from Mount Skardsheidi, past Mount Esja and ravaged it’s way over the lowlands, where settlement spread out , a glittering winter city, on the northernmost shores of the world.

Arctic Chill: An Inspector Erlendur Novel
By Arnaldur Indridason

Made it to Mount Skardsheidi, 42.1 miles into my journey. I did get a real ride in today, including some singletrack riding in at Paris Mountain in South Carolina. See the photo of the very cool rock building at the park. My real ride was at 41 degrees, a sunny Sunday; my virtual ride at 17 degrees.
I like this description above that includes a mention of Mount Skardsheidi, and gives an imdication of what it can feel like there in winter. The  mountain is part of an extinguished volcano known as Skardsheidi is about 4 million years old.
