uKoyal cananian Air iorce GLACIERS GOUGED THE EARTH AND LEFT A LAND OF COUNTLESSLAKES A Dominion Government aerial mapping plane made this oblique view of Sturgeon Lake, west of Lake Nipigon,which ischaracteristic of much ofthe country in the far-flung Canadian Shield (page 773). The waterways are clear and blue where they lie in a rocky basin. Great Bear Lake looks like the sea. But Lake Athabaska, fed by rivers that lie off the Shield, is dull gray, particularly at its western end. St. Anthony Gold Mine is in the middle foreground.
