August 18th.- 
M arched 18 miles up the canon. Passed the well-known 
two-story house f of a mile above and made a front sketch from 
below. Some miles above this there is a group of pretty well 
preserved but small houses high in the cliff to the left; count¬ 
ed nine. Abbut nine miles above camp and f of a mile below 
out last canon camp of the preceding trip, I examined a cliff 
house that is in about as perfect a state as any below. It is 
near the trail and not more than 50 feet above it, but out of 
sight. The pottery debris will reveal it easily. 
August 19th.- 
Marched up the Maneos to the ranch, thence 5 miles Eastward 
and camped on Willow Creek. Before leading the canon de Mancos 
I climbed to the foot of the lower escarpment to examine the 
transition beds. The exposure was not good. All that could 
be seen was shale and clay interbedded with sandstone. There 
were quantities of crystals of gypsum. The sandstone contained 
many fucoids, it is 500 or 600 feet from the Rio to the base 
of the escarpment. The lower part is of shale; dark, homogenous. 
The Mancos in th„ upper hal£ of its course is a sparkling mountain 
stream; in the lower half a sluggish ditch hidden stream, thick 
with mud for the greater part of the year. The valley is not 
wide; ranging from 40 yards to neariy hal£. a mile of bottom-land.
