The Ucayali is just a tributary

Nothing prepares you for the size of the Amazon. As we flew over the jungle on our way to Pucallpa, I looked down and saw a huge river snaking through the forest. Enormous.

I later learned I was looking at the Ucayali--a small tributary that feeds the much larger Amazon which is several days past Pucallpa by river boat.
