Load of rocks from Alberta

I managed to get a load of rocks out from Alberta thanks to my friend from Alberta!

Here’s what they look like. I loaded the larger ones onto my 3lb tumbler and will see what’s up after a week or so.

There is a piece that may be petrified wood. I wanted to reassess if I should tumble that one and if I do I want to make sure I know the hardness so it can go in with similar stones.
