Prairie Woods Environmental Learning Center outside New London, Minnesota is a tremendous resource--and a fabulous place for the occasional picture. More information about PWELC is available on their website at http://www.prairiewoodselc.org/

Note: For some reason the saturation isn't as great on Pbase as it is otherwise; I did make sure to convert the color space to sRGB prior to uploading it. In any case it was a lot more spectacular in real life...
