Time Traveller

You walk to the west, and hear a roaring of falling water. You walk around a corner and are greeted with a dense and lush forest, with a massive waterfall pouring off the cliff. You stand and star at it's magnificence for a while, and then see some tiny chicken sized dinosaurs that are clambering over the rocks at the base of the waterfall. You quickly take a photograph, and then wonder what to do next.
