Running our boats up into the mouth of a quiet river entering from the left we tied them up and were quickly established in the most comfortable camp since Brown's Park.

We were at the mouth of Yampa River.

From a wonderful echo which repeated a sentence of ten words, we called the place Echo Park.

Such an echo in Europe would be worth a fortune.

The Echo Rock is shown on page 203.
Here a stop was made for several days, and one evening some of us took a boat and went up the Yampa a little distance.
