Fig. 12. View of the cat-tail vegetation mat in Montezuma marsh in early 
spring and during an abnormally low-water stage. The ridged effect is prob- 
ably due to violent wave action during high winds which have clean sweep 
across the marshes.

Fig. 13. A glacially filled streamway near Wanakena showing typical 
marsh-meadow. The grass is chiefly Calamagrostis canadensis but there 
are also sedges, etc., and a good deal of Sphagnum. The conifers are 
balsam*and black spruce.
