Day at the Pogue

December 13, 2012 Posted by: G. MacMaster

On September 25, 2012 Mrs. Stainton's Integrated Environmental Science classes took a field trip to the Pogue. While there we spent time collecting dragonfly nymphs for a several month long science experiment about mercury in our environment. We will be using dragonfly nymphs because they are relatively high on the aquatic food chain and they don't move from their environment for several years, allowing for mercury to bioaccumulate in their body. Our classes were split up in to 10 small groups and we spent around an hour collecting nymphs. To collect them we used nets to scrap the bottom of the pond to search for nymphs. After collecting our samples we used "clean hands, dirty hands" to make sure our samples wouldn't get contaminated. We will be sending these samples to Dartmouth College to be analyzed and the mercury content found and sent back to us to analyze.

Conservationist George Perkins Marsh, for whom Marsh-Billings-Rockefeller NHP is named, championed the creation of a US Army Camel Corps. On El Morro National Monument's Inscription Trail you can see the inscriptions the Camel Corps left behind in 1855.
