Temperature of Milk R. 8 A.M. 62" water greenish-white probably giving rise to name.

Aug 6. Left camp at 6 A.M. & continued ascending almost uninterruptedly till we reached the E. bank of the valley of the third branch of Milk R. From this point a splendid view of the mountains obtained & in the middle distance a succession of wave like ridges one behind another running parallel with the base of the mountains. The valley of the river is here double. A very wide gently sloping one & in its bottom another ditch-like & deep in which the river serpentines, doubling on itself & touching the base of the bank at every bend. The water of similar milky hue to that seen in the river before, but not so much so.

Examined section in bank while lunch preparing.
