They are called striations.
striations
Striae.
When glaciers move as they grow, they grind the ground and rock underneath them. These pieces are pushed forward while they grow. When they final begin to melt, the water that is in the glaciers flows out from underneath them. This often carried sand and small bits of gravel. As they melted further and faster, larger gravel and stones wash out. Finally very large rocks and boulders are left behind. All of these are called deposition.
because a space man crashed into it:]
It is sometimes referred to as a 'scratch coat' or 'parge' or 'pargeing'.

As glaciers move over Earth's surface, the ice acts like sandpaper. The scratch marks that are visible when the ice melts are called striations.
The small glaciers that exist in high mountainous areas were called mountain glaciers or cirque glaciers.

You must mean left begins by glaciers! Well there was big boulders for starters. And I think as they receded they left big hills and valleys called coulees! Hope this helps!
its not mountain glaciers but its valley glaciers
The process of becoming covered by glaciers is called glaciation.
i think the rivers of ice in Antarctica are called glaciers.
Valley Glaciers :)
It is called "sgraffito" the Italian word for scratch.
