probably is still so known in that region, though on the maps 
it was afterwards changed by Powell to Fremont River, in 
honour of the Pathfinder. 
They were now in the beginning of what has since been 
called Glen Canyon. Powell at first gave the name of Mound 
to the upper half, and Monument to the lower, but after 1871 
Glen was substituted for the whole. On July 31st they passed 
the mouth of the San Juan, which enters through a canyon 
similar to that of the main river, about a thousand feet deep. 
They tried to climb out near this point, but failed to accom¬ 
plish it. The next day they made camp in one of the peculiar 
alcoves or glens from which the canyon is named, worn by 
the waters into the homogeneous sandstone composing the 
walls. This particular glen is a beautiful spot. The wide 
entrance contains a number of cottonwood trees, and passing 
these one finds himself in a huge cavern some five hundred feet 
wide and two hundred feet high, with a narrow slit leading up 
to the sky, and extending back far beyond the limits of the 
glen. The men found this a delightful place. They sang 
songs, and their voices sounded so well that they bestowed 
upon the cavern the name of Music Temple. It now holds a 
special interest because three of them, O. G. Howland, Seneca 
Howland, and William Dunn, carved their names on a smooth 
face of rock, and it forms their eternal monument, for these 
three never saw civilisation again. 
For 149 miles the easy waters of Glen Canyon bore them 
along, and by August 4th they had passed the Crossing of the 
Fathers, or Ute Ford, as it was called in that country before 
its identification as the point where Escalante crossed, and 
were at the mouth of the Paria, since 1873 better known as 
Lee's Ferry. They had now before them the grandest of all 
the gorges, though only two hundred feet deep at the begin¬ 
ning; but they had not proceeded far into it before the walls 
ran rapidly up while the river ran rapidly down. Numerous 
falls appeared, one following another in quick succession, neces¬ 
sitating portages and much hard work. When Powell managed 
to climb out on the 7th, the walls had grown to twenty- 
three hundred feet. They soon increased to about thirty-five
