I know of a few places where a strong aroma alerts you to it long before you arrive.
One I discovered during my time as a cruise ship naturalist in the Great Lakes. Mackinac Island in Michigan has no automobiles so horses are everywhere.
Penguin colonies in Antarctica and South Georgia also have a strong smell.
I thought of this today as I entered the breeding colony at Tommy Thompson Park.
Cormorants, gulls and night herons all breed here. As it is September all but a few chicks are out of their nests.
All birds feed their chicks by regurgitation.
Cormorants in Antarctica are black and white and are called Blue-eyed Shags.
The woods grew dark, as though they knew no noon;
The thunder growled about the high brown hills,
And the thin, wasted, shining summer rills
Grew joyful with the coming of the rain,
And doubtfully was shifting every vane. – William Morris (1834—96)
