These marks are called striae and are the parallel marks left on the bedrock when rocks entrained in the glacier scrape along the glacier's base.
.
These are part of the origin of the features called moutonne roches = rock sheep. Which were NOT your usual merino, but were the nick name given to judges wigs, which, when lying on the bench, had similarities with the geological features; the shape being similar, and the striae resembling the marks left on the rock. At least according to some authorities such as Holmes.

What is a glacier groove?
a glacier groove is when it scratches or gouges or cuts into bedrock's by the process of glacial abrasion.
A geologist finds deep gouges and scratches on bedrock in an area once covered by a glacier These scratches are evidence of the type of erosion called?
Plucking
What are glacial striations and glacial erratics?
Striations are "scratches" left in bedrock by glaciers. A small particle of rock, generally pebble sized or smaller, becomes entrained in the base of the glacier and dragged along the surface of the bedrock. These can often be seen on hard bedrock surfaces that are resistant to subsequent weathering after the retreat of the glacier. Erratics are large rocks that are found out of place in the landscape, i.e. not near where they were formed. They are removed from their provenance by a glacier and transported away, before being deposited in a different part or the landscape when the glacier melts.
Is glacier canyon a real glacier?
yes glacier canyon is a real glacier
Do glaciers cause water erosion?
Glaciers cause erosion because of the immense weight and pressure they can exude onto surfaces. Fine grains of sediment get lodged into the bottom and sides of the glacier, making it so abrasive that it scratches grooves into rock as it moves.
What erosional agent produces grooves and scratches?
A glacier produces grooves and scratches.

What are the grooves and scratches left in a rock by a glacier called?
Crevasses

How do melting glaciers shape land?
When the glacier is formed the ice scratches the land. When the glacier recedes the ice will scar the earth. This is called glacial scarring.
What is the process that the rocks dragged by glaciers produce grooves and scratches in bedrock is this the definition?
By the passing by of a glacier.
How does rocks look after being dumped by a glacier?
after being all dumped out, the rocks might have deep scratches and marks.
What can occur as glaciers remove loose pieces of rock or as dragged rock scratches rock underneath the glacier?
something.
Which agent of erosion deposits irregular mounds of unsorted sediment with parallel scratches on rounded particles?
It is produced by the movement of a glacier
Rocks at base of advancing glacier?
The embedded rocks grind away the bedrock beneath the glacier, leaving scratches, striae, on the rock. In doing this, they tend to round off the corners of all but the largest boulders, and produce huge quantities rock flour. The smaller rocks tend to polish the basement. If upstream there is a harder rock, such as volcanic or granite, then the bed will be more deeply excavated than if all the grind stones are homogeneous. The rocks enter deeply into the glacier at bergschrunds (crevasses at glacier edge), or through ordinary crevasses where the glacier goes over a step in its bed.
What are some names of glaciers in Washington?

Is the snowball glacier continental glacier or valley glacier?
It is a valley glacier
