Cheltenham Badlands......

is not far from where we live. “Badlands is a geologic term for an area of soft rock devoid of vegetation and soil cover that has become molded into a rolling landscape of rounded hills and gullies. Such areas are rare in Ontario and this is one of the best examples. They exhibit the reddish hue of the Queenston Shale that forms them. It is the presence of iron oxide in the shale that accounts for the red colour. The narrow greenish bands that can be seen throughout the shale are due to the change of red iron oxide (iron III) to green iron oxide (iron II) brought on by the circulating groundwater. The relatively soft shale is essentially clay and easily eroded by water. " quoted from this site

Now normally they look a lot redder, but we have had so much rain this year and we had a lot of rain overnight, so they look darker and more browner than they normally look. My photo's don't do them justice, there are other photo's on the Internet, and here is a site to see a better photo

Here are my photo's.
