The valley of Roaring Fork, for some distance south of Grlenwood, is 

 an anticlinal valley. That is, the bounding ridges on the west have 

 the western dip of the upturned fringe of beds along the western flank 

 of the Rocky Mountain uplift, while in the hills on the east the beds 

 have a Blight dip east toward (he triangular synclinal area included 

 between the Elk mountains, the Sawatch range, and the White River 

 plateau. For the first part of the way the valley bottom is in the softer 

 beds of probable Carboniferous age, immediately underlying the red 

 sandstones of the Trias, which are seen in the hills on either side. The 

 valley contains a great amount of glacial debris, often arranged in 

 flood-plain terraces, and increasing toward the upper part of the valley. 



At Cardiff station are extensive coke ovens. Here a short branch 

 line comes in from the west which brings coal from large mines at Sun- 

 shine and Jerome Park, in a monoclinal valley in Cretaceous strata 

 beyond and parallel to the ridge bounding Roaring Fork valley on the 

 west. 



About 12 miles (19 km.) from Glenwood the valley forks, Rock creek 

 coming in from the north to join Roaring Fork. From here one has an 

 uninterrupted view of Sopris Peak, which ties between these two 

 streams. The general structure of the peak, 61 with the sedimentary 

 beds sharply Upturned around the dioritic core, can readily be distin- 

 guished in clear weather, and in the distance, up Rock Creek valley, 

 one can see the high summits of the Ragged Mountain group, composed 

 of laccolitic bodies of porphyry intruded into Cretaceous strata. 



All the way up the valley of Roaring Fork, above Rock Creek, occa- 

 sional glimpses are obtained, over the intervening ridges, of the grace-
