Plate 46.-Two habitats are shown here. Classification of exposed areas: SYSTEM Lacustrine, subsystem Littoral, class Uncon- 

 solidated Shore, SUBCLASS Mud, water regimes Intermittently Flooded (light-colored soil) and Seasonally Flooded (darker soil 

 along water's edge), water chemistry Mixosaline, SOIL Mineral. Classification of inundated areas: system Lacustrine, SUB- 

 SYSTEM Littoral, CLASS Unconsolidated Bottom, subclass Mud, WATER regime Semipermanently Flooded, water CHEMISTRY 

 Mixosaline, soil Mineral. Greasewood (Sarcobatus vermicidatus), salt grass (Distichlis sjricata), and rushes (Juneus spp.) are scattered 

 across the flats. Because annual precipitation averages only about 18 cm (7 in) here, these wetlands are heavily dependent upon 

 snowpack in the surrounding mountains as a source of water. (Saguache County, Colorado; Photo by R. M. Hopper)
