Iguazu Falls, Argentina

April 21, 2010

I wanted to share with you this picture I took 3 weeks ago, in Iguazu Falls, Argentina.

It was almost 1700 hours, and it just stopped raining.

Can you tell me what this is?

Editor's Note: I asked Ximena if anyone had seen the object, and here is her response.

It was me and my husband only, and a Mexican couple who took the picture for us. But we didn't see anything unusual. As it was a rainy day, there were few people there.
