Beneath the Folds

May 4, 2016

Many and many an eon ago,

the earth upon itself did flow.

Magma splattered; lava rolled,

laying earth in fold on fold.

LavaFlow

While peaks poked up in seismic lifts

valleys formed in with earthen rifts.

Mountains rose up to skyward dreams

valleys settled into watery streams.

When Man wandered out across this earth

his life came renewed in newborn birth;

our legacy rose up in times of old

beneath the covering of Woman’s fold.

Together, our human adventure we did form

through thick and thin, through calm and storm.

When man’s stony knob doth ascend

Hallelujah! woman’s cleavage doth transcend.

Speculating on a Stratified Story

June 25, 2012

Wandering on a rocky Hawaiian shore we discovered this layer of red rock stratified between two layers of black rock. I was wondering, how did this happen?

I am no geologist, but I have done a little reading about the earth and the rocks within it, and some exploration, as you can see here. That’s my hand in the pic.

In offering a layman’s analysis of this geological puzzle, I must begin with a basic fact: TheHawaiian islands are all exposed parts of one very big volcano, situated on the Pacific Ocean floor three miles below the surface, but extending high enough to protrude into air.

In this particular case, the red strata, formerly hidden within massive black/gray lava fields on the edge of Maui island, has been exposed by the erosive action of nearby ocean waves that have been perpetually crashing upon these rocks for a long time.

What I do now about the black layers is that they are igneous rocks formed by volcanic lava, which had flowed from the erupting earth fissures many years ago.

I’m not so sure about the red streak. My investigating touch (shown above in the pic), indicated that the texture of the red rock is granular, sandy, which is different from the feel of the black layers below and above it. This apparently sandy composition may indicate that the red layer is sedimentary rock. If that is correct, we could say that the red, iron-bearing deposit was laid by weathering wind/water forces, and laid upon the black basalt lava rock below it.

Presuming that my sedimentary assessment contains, perhaps, a grain of truth, we could infer that the red streak may indicate a more recent epoch of time when the volcanic lava flow had ceased, enabling earth processes to leave something different for awhile–say, a few thousand years? I don’t know.

A geologist could tell you. On the other hand, he may blow my whole theory to smithereens, just like the volcano, Puukukui, blew all that black rock into the location you see here.

Whatever that red layer is, obviously it was later covered by a another black volcanic lava flow, and thus was covered for many an eon until the Pacific Ocean knocked the shoreline around and taught it, and us human inquisitors, a thing or two. If you can help me interpret this stratified story, please do. Rock on.

Volcanic Legacy

July 16, 2011

‘T’was many and many an eon ago beneath Pacific deep

the fiery earth spewed out a plume of magma lava creep.

The hot stuff came pouring out so fast from cracks in the ocean floor,

it flowed and popped and fizzled and then it spewed some more.

It piled up so high it reached the top of Pacific ocean waves

with mounds and mounds of lava rock and lumps and holes and caves.

Two miles high the molten stuff came puffing above watery swells;

It sizzled in a burning lump , and looked like a thousand hells.

When at last it settled upon a large and lumpy, bumpy, volcanic shape,

the wind and rain came to do their thing to form Hawaiian landscape.

But that reshaping job would take ages of geologic work,

through which the cone was slowly worn down and lava often would perk.

Then one day a little seed came upon a storm-tossed birdy wing

and nestled itself into the barren rocky dusty sandy eroding volcanic thing.

And so from lifeless lava rock and sterile stony crater dirt

there sprouted up a sprig of grass or lichen or  some other rooted wort.

The little plant popped up a flower and then it dropped a seed;

Yes, there began the slowly spreading plant kingdom proliferating deed.

God only knows what the newly established plant may have looked like,

‘though here’s a fellow who suggests the scene while  on a crater hike:

As  time went by more birds and seeds managed to hitchhike ocean winds,

to  extend the nascent colony ‘s  wispy, leafy, seedy trends.

It may have been a scene like this, with another plant or two,

though disregard the guy who’s standing there to show it all to you:

Meanwhile, in the midst of all the crater’s lava dusty stone,

Now and then the volcano thing would erupt and do a cone:

Eventually, God’s creative work of greening, growing life

established a thriving , spreading colony to break up the rocky strife.

Now here’s a lovely lady who views the crater in today’s volcanic scene,

while hubby snapped the pic; he’s the one in shirt of  plaidy green.

But near the ocean shore below  volcanic magma geology

A big tree grows that surely shows God’s artistic biology.

Now here we depict a God-grown tree, and standing there a fool there be,

to celebrate exquisite biology, that thrives on ancient geology.

Yes, Hawaii is amazing with its volcano, its flora, fauna, and deep blue sea,

simply astounding , overwhelming, mystifying  this birdbrain—me .
