Wauconda Bog Nature Preserve is a tamarack bog located in Wauconda, a suburb of Chicago, located in Lake County, Illinois. It is a National Natural Landmark.〔(【引用サイトリンク】title=Wauconda Bog Nature Preserve )〕 ==Biological history== The Wauconda Bog is a wetland created by the Wisconsin glaciation, the most recent of the so-called ''ice ages'' to affect the Illinois landscape. Core samples have been extracted from the peat layers contained within the bog, and they have told a vivid story of climate change in central North America during the postglacial period. Different levels of temperature and precipitation encouraged the growth of very different kinds of plant life during this period; these diverse species released large quantitites of characteristic pollen, which was trapped within the layers of peat preserved here.〔 Geomorphologists sometimes compare the Wauconda Bog with the nearby Volo Bog, also a National Natural Landmark located about 7 miles (11 km) north of the Wauconda Bog. The two bogs displays different stages of a bog's life cycle. The Wauconda Bog, unlike Volo Bog, no longer has any patches of open water; instead, layers of wet and damp peat support characteristic wetland plant forms such as tamarack, cattails, wetland orchids, yellow birch, and poison sumac.〔
