ATTENTION!!!
There is no longer a "next Sunday" posting deadline. You can grab your camera, take your photo, and post it in this thread any time you wish to.
Hi everyone,
Would you like to participate in the Weekly Photo Challenge? Just take a photo that is your interpretation of the theme and post it in this thread.
- Your photo(s) should be your own, i.e., they should not have been taken by someone else.
- Photoshopping is allowed but should be kept to the basics only rather than a total transformation.
- Grab your camera, experiment, and, most of all, have fun.

Just outside of Yellowknife, Northwest Territories, Canada. The exposed rocks are precambrian and form the Canadian Shield which is more than 3.96 billion years old. (If there are any geologists here. they can correct me, but this is correct according to Wiki and what we learned while up there in October.)  |

Wow.
I would love to know how on earth they can come up with things like that. It has got to be guesswork. Because no matter how clever, machines can only put out what a human has entered in the first place . . . purely by guessing.  |

Whippet ... geology is very complex. They actually can narrow down times within a few hundred million years.  BTW, the pinkish rocks shown in my photo have been eroded over the eons and most recently scoured during the last glaciation and the many many previous glaciations...remember we are currently in an interglacial which is a boon to humans. Where I live, there was a kilometer-deep ice sheet just 18,000 years ago. And that melted rapidly over a few thousands years. Thanks heavens we are not in an ice age. |

I have seen a programme on TV tonight. Apparently Canada and Russia dispute as to which of them is the coldest country on earth.
The colours in your picture are really amazing, Clive.

The rocks are reddish-pink. The foreground red plant is bearberry ( Arctostaphylos uva-ursi) that is very widespread and grows in the mountains west of us. It is normally green, but turns burgundy in in fall although actually an evergreen woody plant. We were there in October and overnight temps were getting cold. "Apparently Canada and Russia dispute as to which of them is the coldest country on earth." HA! Hardly a contest anyone would want to win. Been well above normal here the past month after a very cold Sept and October. Clive |

Not 4 billion but a mere 400 million year old collection of fossils found locally. They started life as corals and sea shells back when this area was a shallow tropical sea, close to the equator and long before Dinosaurs and when Europe decided to break off from North America and open up the Atlantic Ocean (just a short 150 million years ago!)

kdcintx, great finding! I really like how you included the human element in your shot. It helps us gauge the size of the dinosaur footprint. Very clever! |
