Lyrics:

 

There’s a place called Purgatory Chasm, I don’t know if you’ve heard

The geological features you’ll find there are really just absurd

Weathering, erosion, glaciers and fault lines

Maybe we can find out how it formed when we see all these signs

 

There are so many different rocks in this little scar

Granite Gneiss, Quartz, Pegmatite and even Feldspar!

Feldspar is the most abundant mineral on our planet

But always remember, kids, don’t take feldspar for granite!
 

There’s a place called Purgatory Chasm, I don’t know if you’ve heard

The geological features you’ll find there are just absurd

Weathering, erosion, glaciers and fault lines

Maybe we can find out how it formed when we see all these signs

 

Many people ask, “How was Purgatory formed, deary?”

I say maybe it was Crosby’s keystone fault theory!

No! It must have been the Waterfall Theory from Lougee

Uh oh, here comes the chorus, guess you’ll have to wait and see

 

There’s a place called Purgatory Chasm, I don’t know if you’ve heard

The geological features you’ll find there are just absurd

Weathering, erosion, glaciers and fault lines

Maybe we can find out how it formed when we see all these signs

 

Neither of these theories could actually be possible

It was actually a fault line AND a glacier, isn’t that comical?

The fault line shifted and then a glacier moved through the crack

The scratches on the side prove that water couldn’t have done that.

 

There’s a place called Purgatory Chasm, I don’t know if you’ve heard

The geological features you’ll find there are just absurd

Weathering, erosion, glaciers and fault lines

Maybe we can find out how it formed when we see all these signs

 

Now time for the Bridge:

Root wedging!

Frost wedging!

Abrasion!

Hydrolysis!
Oxidation!

Organic Acids!

Spheroidal Weathering!

These are found at Purgatory!

 

There’s a place called Purgatory Chasm, I don’t know if you’ve heard

The geological features you’ll find there are just absurd

Weathering, erosion, glaciers and fault lines

Maybe we can find out how it formed when we see all these signs
