Colorful confluence
Posted by Callan Bentley
NASA’s Earth Observatory posted a colorful confluence image last Thursday, and it reminded me that I have a similar site of my own to share.
This is on the Icefields Parkway, north of the Athabasca Glacier and Snow Dome, a hydrological drainage triple point. Here, we’re a short distance into the Arctic Ocean drainage. (West of Snow Dome, the rivers drain to the Pacific; southeast of it, they drain to Hudson Bay.)
A blue stream (closer) merges with a dishwater gray stream (further away).
… and as they mingle their waters, they flow off towards the north, towards the Arctic.

Reminds me of my trip to Grand Teton in Jacksonhole Wyoming!
Gotta love geology!
