Athabasca Glacier on the Columbian Icefield

On our way from Jasper to Emerald Lake we paused for a tour of the Athabasca Glacier on this most amazing vehicle - see extra blip.  Then onward.

Another bear on the side of the road and then finally arriving at Emerald Lake.  I now know that this colour of the lakes and rivers is caused by "rock flour", which is fine-grained, silt-sized particles of rock, generated by grinding of bedrock by glacial erosion.

Not a low of people know that!
