Geological time scales

It's easy to forget how old even some of the more recent buildings in India are. The Red Fort in Delhi, for example, was built by one of the last Moghul kings (before they lost their empire to the British). When it was built, water was pumped up from the Yamuna river and used to keep the palaces cool.

Now, though, the Yamua river is more than a mile away. The river has moved that much since the time that the fort was built.
