Background. Aseptic meningitis is an illness characterized by serous inflammation of the linings of the brain (i.e., meninges), usually with an accompanying mononuclear pleocytosis. Clinical manifestations vary, with headache and fever predominating.
Lake Superior 1  ... is the largest freshwater lake in the world by surface area and the third largest by volume (Lake Baikal in Siberia and Lake Tanganyika in East Africa contain more water). 2  could hold all the water in the other Great Lakes, plus THREE MORE Lake Eries. 11,000 years ago: Glacial Lake Duluth, the precursor to Lake Superior, forms as the ice sheet retreats northeastward. 2  The lake's torrential outflow near present-day Duluth carves the St. Croix River Valley and feeds the Mississippi River.
Continued wet weather contributed to Lake Superior finishing the quarter 15 cm (5.9 in) above its long-term average and 20 cm (7.9 in) above last yearâs level. Lake Michigan-Huron continued to rise, finishing the quarter just 2 cm (0.8 in) below average, but 42 cm (16.5 in) higher than last yearâs level.
