Perch of the Devil by Gertrude Atherton — Read

Butte, "the richest hill in the world" (known at a period when less famous for metals and morals as "Perch of the Devil"), is a long scraggy ridge of granite and red and grey dirt rising abruptly out of a stony uneven plain high in the Rocky Mountains. The city is scooped out of its south slope, and overflows upon The Flat. Big Butte, an equally abrupt protuberance, but higher, steeper, more symmetrical, stands close beside the treasure vault, but with the aloof and somewhat cynical air of even the apocryphal volcano. On all sides the sterile valley heaves away as if abruptly arrested in a throe of the monstrous convulsion that begat it; but pressing close, cutting the thin brilliant air with its icy peaks, is an irregular and nearly circular chain of mountains, unbroken white in winter, white on the blue enamelled slopes in summer.

For nearly half the year the whole scene is white, with not a tree, nor, beyond the straggling town itself, a house to break its frozen beauty. It is only when the warm Chinook wind roars in from the west and melts the snow much as lightning strikes, or when Summer herself has come, that you realize the appalling surface barrenness of this region devastated for many years by the sulphur and arsenic fumes of ore roasted in the open or belching from the smelters. They ate up the vegetation, and the melting snows and heavy June rains washed the weakened earth from the bones of valley and mountain, leaving both as stark as they must have been when the earth ceased to rock and began to cool. Since the smelters have gone to Anaconda, patches of green, of a sad and timid tenderness, like the smile of a child too long neglected, have appeared between the sickly grey boulders of the foothills, and, in Butte, lawns as large as a tablecloth have been cultivated.
