On our visit to Utah last year we came across this large hole in a rock face, and at first sight it didn't look very interesting.
When it started raining, we walked around the rock, searching for a place to shelter. When we got to the other side, we saw this huge half dome with the hole in the distance. It was a spectacular sight, but as often with scenes like this, it was hard to get a sense of scale in the photograph.
I asked my wife to climb up to the window and stand in it, and that made all the difference. After a couple of shots the setting sun briefly peeked between the clouds and colored the rocks near the window deep red.
I was very happy to hear that this image was awarded a Highly Commended at this year's Nature's Best International Photography Awards.
