predominate over the lead and the gangue is 

 essentially quartz. Slocan lake is of the same 

 type as Kootenay and the Arrow lakes. The 

 several features, however, of mountain peak, 

 glacier and delta give it a beauty peculiarly its 

 own and by many is considered the most beauti- 

 ful lake from a scenic view point in southern 

 British Columbia. 



The lower half of the lake is eroded in the 

 granitic rocks of the Nelson batholith, the main 

 part of the upper half lies on the contact of 

 those rocks with those of the Slocan slates. The 

 form of the lake is bow-like with the convex 

 side to the east. It has a length of about 25 

 miles (40 km.) and an average width of one 

 mile (i-6 km.) with a low water elevation of 

 1,761 feet (537 m). Two soundings, one near 

 the south end and one opposite Roseberry 

 give respective depths of 925 and 765 feet (282 

 and 233 m.). 



Silverton is situated on the delta of Four- 

 mile creek. It is the distributing point for 

 several silver-lead mines, the more important 

 being the Standard, Hewitt and Van Roi, and 

 the L-H gold mine. 



New Denver is situated on the delta of 

 Carpenter creek and is within easy distance of 

 the majority of the most important silver-lead 

 and zinc mines of the Slocan district, the prin- 

 cipal centres being Silverton, Sandon, McGuigan 

 and Whitewater. 



Silver-Lead and Zinc Deposits. 



The district in which productive ore bodies have been 

 found comprises the Ainsworth, Slocan and Slocan City 

 Mining divisions. The district lies within the Selkirk 

 system of the Cordillera and is characterized by strong 

 relief showing all the more prominent features of alpine 

 topography. The maximum vertical range between mount- 

 ain peak and valley is over 6000 feet (1828 m). Most of 

 the veins occur well up on the mountain slopes and 

 consequently the mines are invariably developed by series 

 of tunnels.
