The Crossing probably wholly melt away later in the summer. The 
en naked, jagged forms of rock have also disappeared; 
and in their stead we have an even, continuous, 
thickly wooded mountain chain, with narrow valleys 
and ravines, from which cool mountain streams gush 
forth. This chain stretches in a rather straight line 
from north to south, and then, forming an acute an- 
gle at the southern end, extends northwestwardly be- 
tween the Bear River and the Snake River. On the 
eastern slope of these mountains several brooks arise 
which all pour into the Green River; from the north- 
western slope come the waters which flow toward the 
Bear River. We descended about eighty miles in 
southwestern course along the eastern slope, and 
crossed the acute angle above mentioned to reach the 
northwestern slope. On the first day we made only 
eight miles. We crossed Horse Creek and camped 
on Lead Creek. The road led over plateaus toward 
the mountains. The next morning we were still in 
similar country, but at noon we reached a little mea- 
dow, enclosed by steep heights, through which mean- 
ders a rippling brook with cool water. From now on 
we had to wind our way through wooded hills. We 
generally followed the course of brooks through nar- 
row ravines, on whose steep sides the animals had to 
climb in single file in a long line. On both sides were 
acclivities, often very steep, overgrown with heavy 
pine and cottonwood. At times we had to clamber 
over the mountains themselves through thick pine tim- 
ber to get from one ravine to another. The geologi-
