EVENT: Snowshoeing the Gneiss SNA with Don Robertson
January 24, 2015 @ 12:30 pm - 3:00 pm
This afternoon trip will be lead by CURE Board Member Don Robertson. Robertson has lived most of his life in the Minnesota River Valley and is a certified Master Naturalist.
Join us on Saturday, January 24th, to snowshoe with other outdoor enthusiasts through the Gneiss Outcrops Scientific & Natural Area (SNA). The Gneiss Outcrops, 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.
The outing is pending weather conditions. Participants should dress in layers, bring water and a snack. Bathroom facilities are not available. We have access to a few pairs of snowshoes but they are limited so register early
Date: Saturday, January 24th from 12:30 to 3 PM
Location: Meet at the Yellow Medicine County Museum parking lot at 12:30 PM and will carpool
Fee: CURE Members are free; Public is $5/person
