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.
Fire and ice, in the form of volcanoes and glaciers, created Lake Superior. That happened long before Jake came here to fish. One billion years ago, molten basalt erupted from the mid-continent rift, which extended from near Thunder Bay, Ontario, to Kansas.ire and ice, in the form of volcanoes and glaciers, created Lake Superior.

Lake Superior (Figure 4) is the largest, deepest and coldest of all the Great Lakes. At 31,700 square miles (The Great Lakes, 1995), Lake Superior is the largest freshwater lake in the world by area. By volume, it is the third largest with a total of 2,900 cubic miles (The Great Lakes, 1995).
