What is this strange rock?

Question

I went camping in whitney lakes campground in alberta canada and decided to go to the beach when I went swimming i found a strange rock!Its grey with scattered crystals with a little bit of white. I also found out that a glacier passed through about 10,000 years ago is it maybe a glacier rock?I have looked all over the internet and cant get answers!!!

Answer 1

It could be a dimictite if it is poorly sorted.  That pretty much means that the glacier dropped stuff of all sizes.  

Answer 2

Without actually seeing it, it's hard to say... it sounds more igneous than anything else.  There's no such thing as a "glacier rock", by the way.  Rocks can be deposited and eroded and reshaped by glaciers, but glaciers don't actually form them.

Answer 3

Glaciers can transport rocks long distances and then deposit them as they recede.

Without seeing it - its hard to identify - how big are the crystals.

It sounds vaguely like an igneous rock made of feldspar and quartz - but who knows...

Answer 4

I guess I am fix'n to show my ignorance, but aren't glaciers made of ice?  Maybe they have rock in them?

Answer 5

What you may be seeing is what is called a Glacial Erratic.  It is bedrock that has been transported many miles (perhaps hundreds) from its original place and dropped when the glacier receeded.
