WEBEE CANON. 385 



sandstone, with a decidedly arenaceous habit, which is probably at or near 

 the line of junction of the Wahsatch limestone and "Weber Quartzite, 



To the north and east extend flat plateau-like hills, formed in general 

 of beds of the Vermillion Creek Eocene, in some of whose ravines are, 

 doubtless, exposures of underlying rocks, which may not have been indicated 

 on the map. In general, however, these beds close up around the flanks of 

 Morgan Peak. On the west side of the peak, toward Morgan Valley, the 

 slopes are generally covered with ddbris and soil. In some of the deeper 

 ravines, however, the Ogden Quartzite could be recognized under the main 

 body of limestone, represented by beds of pure white quartzite, whose thick- 

 ness could not be determined, and forming the face of clifl's, under which 

 the Ute limestone is exposed in a thickness of about 800 feet. Below this, 

 though not actually in contact, is a body of greenish clay-slates, somewhat 

 micaceous, underlaid by a body of yellow and pinkish, rather granular 

 quartzite, representing the Cambrian. These rocks were observed in the 

 foot-hills, a few miles north of Weber Station, having a strike of about 

 north 35° west. The lower members are soon lost to the westward beneath 

 the valley-beds. 



At Weber Station, the hills to the north present the ends of strata 

 of the Wahsatch limestone, varying in strike a few degrees to the east or 

 west of north, and dipping eastward at angles from 28° to 40°. The beds 

 are usually of quite pure limestone, some highly crystalline, others merely 

 granular, and still others quite earthy, and containing well-preserved fossils 

 of the Lower Coal-Measures, among which were recognized: 



ZapJirentis Stansburyi. 

 Chonetes granulifera, 

 Productus symmetricus. 

 StreptorhyncJms crassus. 

 Martinia lineata. 

 Spirifer opimus. 

 Sph'iferina Kentuckensis. 

 Athyris suhtilita. 



Passing up the canon, the same limestones form the hills on the north 

 of the river for 2^ to 3 miles, a continuous series of about 5,000 feet
