I. Looking across Columbia River Valley to the west face of Stanford 

 Range between Stoddart Canyon on right and Dry-Creek Canyon on left. At 

 the mouth of Stoddart Canyon the Upper Cambrian Lyell ? limestones (L.) 

 form a low cliff and to the left of the canyon foothills of Mons shales and 

 limestones (i\l.) abut against the cliff's of Silurian Brisco (B.) and Beaver- 

 foot (Br.) limestones. The strike of the IMons and the Silurian strata is 

 indicated by short lines and the position of the fault between the Mons and 

 the Brisco limestones by a dotted line. A second block of the Alons and 

 Silurian further up Stoddart Canyon is indicated by the letters M., Br. The 

 Red Wall fault and breccia are shown on the face of the high cliffs to the 

 left, which are a short distance south ot Sinclair Canyon. (Photo by Wal- 

 cott, 1923.) 



2. Southwest end of Sabine Mountain. The Silurian Brisco and Beaverfoot lime- 

 stones form the higher cliff beneath which the lower Mons shales and limestones 

 (M) slope down to contact with the Upper Cambrian Lyell ? limestone (L). The 

 position of the fault that has brought the lower limestones against the Lyell ? 

 is indicated by a dotted line. (Photographed by Walcott, 1923. from bluff above
