The boulder clays are often overlaid and underlaid, 

 and more rarely interbanded with stratified clays, sands 

 and gravels. 



The estuarine deposits, mostly dark, plastic, strati- 

 fied clays with associated sands and gravels, have been 

 largely destroyed along the valley of the Skeena, and occur 

 only in isolated patches. No fossils were found in them, 

 but similar beds occupying a like position on Bear river at 

 the head of Portland canal contain numerous shells of 

 species still existing in the nearby ocean. 



The estuarine deposits, and the boulder clays along the 

 central portion of the valley, are overlaid by river sands 

 and gravels. The older deposits were cut through as the 

 land rose and the river deepened its channel, and now occur 

 on benches at various elevations above the water level up 

 to at least 300 feet (91 .4 m.).
