Day: August 20, 2010

Is this one too hard? Next Wednesday a hint will be published.

Thanks to all who gave their opinion in the poll.

There were 17 entries made, 16 of them in favour and one ‘No’. Unfortunately the ‘No’ had no comments, so I don’t know the reasoning behind it. It could be very valid, but it was not given.

But based on the results, it might be worth experimenting with the ‘Wednesday hint’, so let’s try it out in the next contests. My ideas, based on your reactions, are as follows:

• The next contests (except the obvious easy ones) will get a ‘Wednesday hint’.
• The hint will be published on Wednesday 0:00 GMT (UTC)
• Correct answers submitted before the hint, will get 1 bonus point.
• In some contests there will be an extra challenge which will give you an additional point (the former ‘+’)

Please feel free to comment.

This is the point where the Yellow River (or Huang He/Hwang Ho) enters the Bohai Sea.

As the Yellow river is the most sedimented river on earth, the delta is an ever changing piece of wetlands. The Earth Observatory site of Nasa has an interesting set of pictures of the changes in the last 20 years.
