Tour Canada from space Norman Wells, Northwest Territories
 Large, stark features blot the landscape on either side of the Mackenzie River as it flows past the small town of Norman Wells. In this false-colour infrared band combination, healthy vegetation is shown as bright red, burnt areas as mottled dark grey/black, bare rock and soil as light blue and white, while the waters range from light blue for the sediment-laden rivers and black for the still, deep lakes. A whisp of smoke coming from the west suggests that nearby forest fires are still not completely out at this date.
Question: Which way does the river (Mackenzie) flow? There are several clues if you look closely at the larger, full'image. [ Answer ]

| Question: |
Which way does the river (Mackenzie) flow? There are several clues if you look closely at the larger, full'image. |
| Answer: |
The Mackenzie is one of the few rivers in North America that flows (generally) to the north. In this image, its flowing from right to left. How can you tell? Look at the islands in the river. Some of them display a raindrop shape, with one blunt and one sharp end. These shapes were carved by the flow of the water (from the blunt to the sharp ends). Another clue is the way the tributaries join the Mackenzie. They tend to join in the direction of the water flow of the larger channel (the Mackenzie). |
