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.

The Lake Superior agate was selected because the agate reflects many aspects of Minnesota. It was formed during lava eruptions that occurred in Minnesota about a billion years ago. The stone's predominant red color comes from iron, a major Minnesota industrial mineral found extensively throughout the Iron Range region.
