Glacial valleys (also known as glacial troughs) tend to be u-shaped, as opposed to river valleys which are v-shaped.
A U-shaped valley, also known as a glacial trough, is a large valley with steep sides, and with a wide, flat valley floor. It is formed, as the alternative name suggests, by glacial activity in the area (i.e. it was formed by a glacier).
Erratics are a key sign of glacial activity. These are large rocks resting on top of soil, unlike monadnocks which are pinnacles left over from riparian erosion. The rock is carried from some distant mountain on glacial ice, and abandoned on a plain when the ice stops moving and melts. Glacial valleys have a characteristic U shape to them, as opposed to the V shape of valleys carved by water. Often glaciers leave broken rock and rubble in a wavey line known as a terminal moraine, or along the sides of the moving ice in formations known as lateral moraines. Ice also gouges series of characteristic grooves or scars on mountain rock faces, indicative of glacial activity.

They were the Vikings who came from Scandinavia.
what is this
A glacial deposit is known as a moraine. A moraine may form a dam, keeping back the glacial melt-water, forming a series of lakes.
The exact year is not known. Norwegians are ancestors of Battle-Axe humans who migrated to Scandinavia from "mainland" Europe.
