Day 7: Now at Lake Powell, which is beautiful and awesome but in a completely different way.

We are right out in the desert now, and it's spectacularly hot. To cool down, we take a boat trip to explore some of the colourful and dramatic side-canyons like Antelope Canyon, "the most-visited and most-photographed slot canyon in the American Southwest".

These are some of our fellow passengers in mid-gawp.
