E – eolian sand

Sand dunes (Unit E) in Manitoba are largely a result of the reworking by wind of glaciofluvial sand deposits (Unit Gs). Some sand dunes are also associated with modern beaches (Unit Lm). The largest area of dunes is in Spruce Woods Provincial Park in southwestern Manitoba (Images 12–15), where active and stabilized dunes provide a unique environment for specialized flora and fauna (Image 16).
