Mr. Holmes report on the trip Is found in this 
report on pages 187 to 195. 
The following is quoted from Dr. Hayden’s intro¬ 
duction to this Annual Beport of the Survey: 
"In company with the trlangulatlon party, Mr. 
Holmes made a hurried trip through Colorado, touching 
also portions of Now Mexico and Utah. He was unoh1e 
to pay much attention to detailed work, hut had an 
excellent opportunity of taking a general view of the 
two great plain belts that lie, the one along the 
east, the other along the west base of the Bocky Moun¬ 
tains. For nearly two thousand miles travel he had 
constantly in view the Cretaceous and Tertiary forma¬ 
tions, among which are involved some of the most in¬ 
teresting geological questions. He observed, among 
other things, the great persistency of the various 
groups of rocks throughout the east, west, and north.
