This shard is rather easy to find if you are following the main road to north. Whether you come from west and Fort Warden, or from east and Fort Dragonclaw, or any other location, being aware of a fact that there is a skyshard at this location is enough to find it. It is not on the road actually, but rather close to it. If you come from south you can spot it from a small hill. Although there is snow in this part of the map it doesn’t lower the effect of its shine.
Like snow under a sunbeam…
.. it shines brightly.
