Glacial polish is a characteristic of rock surfaces where glaciers have passed over bedrock, typically granite or other hard igneous or metamorphic rock. Moving ice will carry pebbles and sand grains removed from upper levels which in turn grind a smooth or grooved surface upon the underlying rock. The presence of such polish indicates that the glaciation was relatively recent (in geologic time scale) or was subsequently protected by deposition, as such polish will be subsequently lost due to weathering processes (such as exfoliation).
You will note that there is a substantial number of rocks at this location which have been affected by the past effects of glacier polishing.

QUESTIONS
Q1. Describe the effect of the "glacier polishing" on the rocks at the site of the co-ordinates, including the texture of the rocks.
Q2 what colour are the polished rocks? Do they differ in colour from the surrounding rocks?
