crossing, by an open and easy pass, the dividing ridge which separates 
the. waters of the Great Basin from those of the Colorado, we reached the 
anches of one of its larger tributaries, which, from the decided color 
of its waters, has received the name of White river. The snows of the 
were now beginning to melt, and all the little rivulets were 
running by in sibeidgic rapidly becoming diffieult to ford. Continuing a 
few miles up a branch of White zreate we crossed a dividing ridge between 
its waters and those of the Uint The approach to the pass, which is

one animal atatime. From the summit we had a fine view of the showy 
Bear River range; and there were still remaining beds of snow on the cold 
sides of the hills near the pass. We descerided by a narrow ravine, in 
which ieee rapidly gathered a little branch of the Uintah, and halted to 
noon about 1,500 feet below the pass, at an elevation, by the boiling point, 
of 6,900 feet above the sea. 
next day we descended along the river, and about noon reached a 
point where three forks come together. Fording one of these with some 
difficulty, we continued. up the middle branch, which, from the color of its 
waters, is named the Red river. The few passes, and extremely rugged 
bie of the country, give to it great strength, and seeure the Utahs from 
n of their enemies. Crossing in the afternoon a somewhat 
oken highland, covered in places with fine grasses, and with cedar on 
= hill sides, we encamped at evening on another tributary to the Uintah, 
called the Tuaheons, fork. The water was very clear, the stream not being 
yet swollen by the melting snows; and we forded it without any difficulty. 
It is a considerable branch, being spread out by islands, the largest arm 
being about a hundred feet wide; and the name it bears is probably that 
of some old French trapper.
