A crevasse is a deep crack, or fracture, found in an ice sheet or glacier, as opposed to a crevice that forms in rock. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces.
Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres, as wide as 20 metres, and up to several hundred metres long.
A crevasse may be covered, but not necessarily filled, by a snow bridge made of the previous years' accumulation and snow drifts. The result is that crevasses are rendered invisible, and thus potentially lethal to anyone attempting to navigate their way across a glacier. Occasionally a snow bridge over an old crevasse may begin to sag, providing some landscape relief, but this cannot be relied upon. Anyone planning to travel on a glacier should be trained in crevasse rescue.
Born blind in the winter with an empty head
The snow covered up the Camry the whole house slept
Drawing pictures in the bed
Waking up and racing down the stairs trying to catch my breath
It's so simple, superman, trick or treat, wet socks
Bike rides in the summer to the best spots
Coulda sworn I was king of the best odds
Runnin round with the dogs in the back yard
Growin never knowin what the past done
Livin life like the mystery of packed lunch
Getting whooped in the playground slashed up
Comin home after school on the last bus
Back then it was all about last
Hit the corner store for the new Fleer packs
Mom was a religion and happiness was a fact
It's a shame how the time goes past
Movin so fast
Its like im movin at lightspeed
Slow down
You need to slow down
Every once in a while sometimes
You'll see how the world goes round
You need to slow down every once in a whiiiiiile
Cuz you don't know you don't know
You don't need to goooo so fast
Things changed in the pop shop got an offer
Packed up moved out down to Colorado
Sunshine clean air not a lot of problems
And that's when I discovered pogs and tamagachi
Time past and the friends found punk yah
Oh whatever man a lot of it was junk
But we loved it made us feel cool little dumb kids
Runnin round just for fun doin dumb shit
I was lightin all my candles on both ends
Warren lake getting drunk wit the friends
I was tryin to stay positive even though I pretended it
It helped cause at home I was lackin a happy ending
For all, saw a lot of tall trees fall
In the name of an addiction my sister taught me to follow
I cracked cleaned up and got the backpack
I swore that I would never go back
Movin so fast
Its like im movin at lightspeed
Slow down
You need to slow down
Every once in a while sometimes
You'll see how the world goes round
You need to slow down every once in a whiiiiiile
Cause you don't know you don't know
You don't need to goooo so fast
Eighteen I decided I was done with it
Hit Seattle with a head full of drum rhythms
Falling in and out of love with these young women
Thinkin they could make a change of the blood given
Nah I was too young too face it
Workin two jobs still thinking I could make it
Local all star still singin from his basement
Finally got a shot and ive been workin everyday since
Found love in a city where the angels fly
Put a record out with josh one made out clime
Came home after two years and playin out rhymes
Just to find my little angel was no more mine
Parted ways with a friend was not easy
Made a leap to the future it got queasy
Started workin on the things that had lost reason
Now im sittin with a pad Movin so fast
Its like im movin at lightspeed
Slow down
You need to slow down
Every once in a while sometimes
You'll see how the world goes round
You need to slow down every once in a whiiiiiile
Cause you don't know you don't know
