an abandoned well
"They told me the place was evil. They told me this in Arkham, and because that is a very old town full of witch legends I thought the evil must be something which grandams had whispered to children through centuries. The name "blasted heath" seemed to me very odd and theatrical, and I wondered how it had come into the folklore of a Puritan people. Then I saw that dark westward tangle of glens and slopes for myself, and ceased to wonder at anything beside its own elder mystery. It was morning when I saw it, but shadow lurked always there. The trees grew too thickly, and their trunks were too big for any healthy New England wood. There was too much silence in the dim alleys between them, and the floor was too soft with the dank moss and mattings of infinite years of decay."
"But even all this was not so bad as the blasted heath. I knew it the moment I came upon it at the bottom of a spacious valley; for no other name could fit such a thing, or any other thing fit such a name. It was as if the poet had coined the phrase from having seen this one particular region. It must, I thought as I viewed it, be the outcome of a fire; but why had nothing new ever grown over these five acres of grey desolation that sprawled open to the sky like a great spot eaten by acid in the woods and fields? It lay largely to the north of the ancient road line, but encroached a little on the other side. I felt an odd reluctance about approaching, and did so at last only because my business took me through and past it. There was no vegetation of any kind on that broad expanse, but only a fine grey dust or ash which no wind seemed ever to blow about. The trees near it were sickly and stunted, and many dead trunks stood or lay rotting at the rim."
"...everything that had ever been living had gone. Five eldritch acres of dusty grey desert remained, nor has anything ever grown there since. To this day it sprawls open to the sky like a great spot eaten by acid in the woods and fields, and the few who have ever dared glimpse it in spite of the rural tales have named it "the blasted heath." -- The Colour Out of Space
