4 P.M.
Shores began to change in the afternoon . Tundra coming down to banks . Began to see rocks on shore -- glad to see them after so much mud and willow flats . At 4 P.M. made Destruction City -- probably twenty-five miles above the mouth of the Rat . Going slower than we thought , as we hoped to make this yesterday . Caught some big trout , very fine to eat . They take the fly splendidly .
