New Mexico Geological Society
Fall Field Conference Guidebook - 8
Southwestern San Juan Mountains, Colorado
Frank E. Kottlowski and Brewster Baldwin, eds., 1957, 258 pages.
The New Mexico Geological Society welcomes you to its Eighth Field Conference. Past field trips have been essentially within the confines of New Mexico, but this year we are visiting the San Juan Mountains of Colorado where the exposed rocks bear significantly on the geology of adjoining parts of our State. The first day road log is from Durango to Silverton with 9 stops along the Million Dollar Highway. The second day road log is from Silverton to Ouray and Ridgeway and return to Silverton. The third day road log is from Silverton to Eureka and return to Silverton. There is also an additional railroad log for the Denver & Rio Grande Western Railroad Silverton to Durango.
