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 receives water from over 200 rivers, the largest ones being Nipigon and the Saint Louis. The lake discharges its waters into the adjacent Lake Huron at its eastern end via the St. Maryâs River. Lake Superior has an average elevation of 600 feet above sea level, and a maximum depth of 1,332 feet.
