A rock shelter (also known as a rockhouse, crepuscular cave, or abri) is a shallow cave-like opening at the base of a bluff or cliff.
Rock shelters form because a rock stratum such as sandstone that is resistant to erosion and weathering has formed a cliff or bluff, but a softer stratum, more subject to erosion and weathering, lies just below the resistant stratum, and thus undercuts the cliff.
Many rock shelters are found under waterfalls.
Rock shelters are often important archaeologically. Because rock shelters form natural shelters from the weather, prehistoric humans often used them as living-places, and left behind debris, tools, and other artifacts. In mountainous areas the shelters can also be important for mountaineers. In western Connecticut and eastern New York, many rock shelters are known by the colloquialism "leatherman caves", as they were inhabited by the Leatherman over three decades in the late 19th century.
In arid areas, wind erosion (eolian erosion) can be an important factor in rockhouse formation. In most humid areas, the most important factor in rockhouse formation is frost spalling, where the softer, more porous rock underneath is pushed off, tiny pieces at a time, by frost expansion from water frozen in the pores. Erosion from moving water is seldom a significant factor.
You run for cover
Stick your head in the sand
You deny you're wrong
Say you don't understand
The ways and means
Don't mean a thing with no green
And your, body of work
Ain't nobody to be seen
The only choice to make is
Paper or plastic
So ya, do something drastic
And ya make it fantastic
You keep on fishin' for
A way to succeed
It's the, only way
For the big dogs to eat
Just ride the wave
Everybody rave
Don't be a slave
To the things you crave
Temptation make you
Want the things you don't need
Buy them, boogie shoes
And spend to
Feed the greed
You spin the wheel
And play the numbers you feel
Bet them double zeroes
And you'll, be a hero
Just ride the wave
Everybody rave
Don't be a slave
To the things that you crave
Feeble
Evil
Boring
People
Sneaky
Freaky
Lonely
Schemers
Fowling
Scowling
Bottom
Feeders
Musing
Amusing
In
Betweeners
Just ride the wave
Everybody rave
Don't be a slave
To the things you crave
