White Snakeroot (Eupatorium rugosum var. roanense) is a common late-summer composite in Great Smoky Mountains National Park, as the meadows of Purchase Knob can attest. And in the early light of a new day it serves as an attractive foreground element, gathering and reflecting the golden tones of dawn from its tiny white clusters, even as I consider its toxicity to cows and through milk to people (Many believe it was milk fever that caused the death of Abraham Lincoln’s mother, Nancy Hanks Lincoln). Late summer is also the time of billowing ground fogs and low cloud masses hugging the valleys of the Pigeon River watershed far below, down Cataloochee Divide and rising into Cove Creek Gap. 

All of this makes for some wonderful moments as the sun lights up the fields and forests around the Southern Appalachian Highlands Learning Center. The forecast of the previous evening seemed to suggest that the following day could be a good time to be on the Knob.  Positioning the camera about two feet behind and slightly above the blooming snakeroot, a focal length of 39mm, just beyond wide-angle range, but wide for a normal image, gave me the angle-of-view I wanted. An aperture of f/22 provided depth-of-field; and a shutter speed of 1/5th second at ISO 200, chosen because of a very slight wafting breeze, gave me an overall medium exposure. From the top of the world that is the Cataloochee Divide there is a peace that is palpable.
