Postcard ES-661272

This is quite an impressive waterfall, but in fact the card I received included more of the image on all four sides, plus green grass at the bottom, and two mysterious red-and-yellow objects, one near the center of the rocks (and the picture), and the other on the far left, just opposite the first object on the far side of the chasm. I wonder if I will ever be enlightened about these mysteries?

Wait a minute! The outline of the first object does appear in the photo here, but it is only a dark silhouette which could easily be a rock. Hmmm!
