Kettle or ice block holes near inner border of delta. 

 Large ledges of Metchosin basalts to west. 



Locality 19 — From 18 across terraced Colwood delta. 



Iron Mask mineral claim on south slope of Mill hill, 

 altitude 631 feet (195m). Contact metamorphosed Van- 

 couver andesites, amphibolites, which have been sheared, 

 solicified, and mineralized, cut by quartz veinlets, and 

 replaced by garnet-diopside-epidote rock, with magnetite, 

 pyrrhotite, pyrite, and chalcopyrite. 



Locality 20 — To the west Sutton limestone quarried 

 for the manufacture of lime. Lime hydrated and used in 

 the manufacture of sand-lime brick. Sand from Colwood 

 sands and gravels. 



Locality 21 — Unfoliated shatter breccia of Wark and 

 Colquitz gneisses. Hybridism and development of horn- 

 blendite. 



Locality 22 — Banded Colquitz quartz diorite gneiss, 

 primary gneiss. Small pegmatite dykes, small faults and 

 contort ions. 



Locality 23 — From 22 over pre-Glacial lowland. Nu- 

 merous ledges of Wark gneiss and small monadnock, 

 Knocken hill, to north, altitude 260 feet (79 m.), and 

 drowned glaciated valley, Portage inlet, to south. 



Pot-hole in Wark gabbro-diorite gneiss, formed by glacial 

 stream descending through a crevasse or by inter-glacial 

 stream. Wark gneiss cut by apophyses of Colquitz quartz 

 diorite. 



Locality 24 — From 23 over pre-Glacial lowland, largely 

 covered by Maywood clays with thin mantle of Vashon 

 drift in places, and a few outcrops of Wark gneiss. 



Maywood clays. Clays used for the manufacture of 

 common brick and tile. Marine fossils. 



Excursion C 2 (Section I.) 



From the Empress Hotel the excursion proceeds west 

 across the Esquimalt peninsula, which is a portion of the 

 pre-Glacial lowland, with numerous small monadnocks or 

 ledges of the crystalline rocks, largely covered by Maywood 

 clays, with a thin mantle of Vashon drift in places. 

 To the east and west of Esquimalt peninsula the 

 drowned submaturely glaciated valleys of Victoria and 

 Esquimalt harbours. To northwest, upland formed by
