Why we were going to look at a lake was beyond my children. We live by a lake and we only look at it if we aren’t close enough to be in it. It took a bit of convincing and explaining for them to understand that we were going to see a special lake. When we arrived at the lovely paved trail along Lake Louise here is was happened: 
My Eldest: “Maman, those mountains look so 3D!”
My Husband: “That’s because they are 3D!”
My Eldest: “Really?”
My Husband: “Yes, those are real mountains.”
My Eldest: “Woah…those are really nice!”

My daughter and youngest took no notice of the surroundings except for the rocks and the water. Despite the glacial water they were up to their knees in it as they clambered over rocks and boulders.
