some mighty mean hombres hid out in the Badlands." But not
“The Morphology of southern Italian Badlands," the title
of an article I ran across recently. 'Badlands' has always
had a romantic sound to it —savage, stark, beautiful, all
that. I didn't know that the English 'badlands' is the
legitimate geological term used in many languages to
describe some of the loveliest geology that our planet has
to offer. Badlands are dry terrain where softer
sedimentary rocks and clay-rich soils have been
extensively eroded by wind and water. They are
characterized by steep slopes, minimal vegetation, and
lack of substantial top soil (called regolith) above the
bare rock. From South Dakota to New Zealand, Argentina,
Spain and the Cappadocia region of Turkey there are
badlands. All badlands, big and small, around the world
have certain things in common; they have canyons, ravines,
gullies, knife-edge divides and, if you're lucky, things
called hoodoos (also called tent rocks or fairy chimneys.
They look like anorexic aliens wearing hats.). Physically,
badlands are widely described as striking, even
supernaturally so, potentially eerie and foreboding, but
especially colorful. Poet Evan Harris says of them in Badlands

Badlands
exist in Italy at various points (all of the images on
this page are in Italy). The folks over near the town of
Atri on the Adriatic about 200 km north of Naples take
their badlands seriously. They call theirs the Circles of
Hell (from Dante's term—le bolge dell'Inferno—
in The Divine Comedy). They even have a 380-hectare
(940-acre) Regional National Reserve dedicated to them).
Elsewhere in Italy, they exist at Val d'Orcia in Tuscany
and down near the town of Aliano in the Basilicata region,
160 km (100 miles) southeast of Naples. “...the origin of biancane is associated with highly dissected surfaces along a reticular system of small joints. In contrast, calanchi [plural] are formed on steep wall-like slopes along larger lineaments where the rate of incision into the slopes surpasses the denudation of the densely vegetated back-slope.”to science portal to top of this page

In truth, the only thing I really knew about "badlands" until the other day was that you can't have just one of them.
