Snowshoeing the Gneiss SNA with Don Robertson

February 8 @ 1:00 pm - 3:00 pm

Snowshoe

The Gneiss Outcrops Scientific Natural Area (SNA), formed approximately 3.6 billion years ago, are among the oldest known rock on the earth’s surface. This SNA’s significance steadily increases as other outcrops along the Minnesota River are exploited for granite mining, housing, and recreational use. These pyramidal outcrops along the Glacial River Warren Valley rise to about 50 feet above the general level of the land, revealing parallel bands of gneisses. Granitic gneiss is light-colored, pink to red; the less common hornblended-pyrozene gneiss is darker, ranging from gray to black.

This afternoon trip is lead by Clean Up the River Environment (CURE) board member Don Robertson. Robertson has lived most of his life in the Minnesota River Valley and is a certified Master Naturalist.
