thicknesses of volcanic fragmentals and flows. Visits were 
made to a number of the important mines, trips were taken 
across some of the high passes in the mountains, and there 
was abundant opportunity to study the effects of the glaciers 
which once occupied the high mountain valleys. 
From Silverton to Durango the route lay along the An- 
imas Canyon which cuts Pre-Cambrian gneisses, granites and 
quartzytes, and lower down this valley a good section of the 
Paleozoic and Mesozoic rocks was seen. 
Every one on the excursion was highly pleased and it was 
a marked success. The success was in considerable prart due 
to the courtesies extended by the citizens of the places visited, 
— especially Aspen, Ouray and Telluride. Among these cit- 
izens should be mentioned Mr. F. T. Freeland of Aspen, and 
Messrs. Collins, E. J. Fields and H. C. Lay of Telluride, and 
Mr. T. L. Walsh, whose guests the excursionists were while 
at Ouray.
