The features on glacially polished rock are called
"striations". They are not really comprable.

Some pictures are:

1. Glacial Striations near Gullfoss

3. Glacial Striations
http://maps.unomaha.edu/Maher/geo330/kirk1.html

"Striations are usually multiple, straight
parallel lines which represent the movement
of the sediment loaded base of the glacier
over. Striae can range from microscopic size
on a seemingly polished rock to obvious
markings millimeters deep and nearly a
meter in length."
