Birth of an Island(WARNING! 108 lines)

Formers of ancient landscape remove clues
 With wind and water in it's many forms
 What we see is since Glaciers took a cruise
 To learn, scholar tests difference from norms

 They've learned that dust unlike that blown down street
 Swirled around in Universe's vacuum
 Eventually clouds of dust did meet
 Formed huge dust whirl in Nebula's back room

 Spinning until heat turned it to magma
 Then the white hot center became our sun
 Flung off into space was thrown off plasma
 Still spinning formed young planets. Earth was one

 Adored moon formed when Molten rock spewed out
 From Earth in rock's wreck. Earth resumed hot spin
 Then formed layers with lightest wrapped about
 They cooled slowly, holding the heat within

 Magma cooled to Basalt to form earth's crust
 Rock eroded by water and wind's gust
 Millions of years of harshest weather days
 Wore the volcanic rock down in the haze

 Laid it back down forming layers of rock
 Divisions made by violent earthquake's shock
 Then volcanic heat or just great pressure
 Changed form of the rock to something fresher

 Life was plants and worms millions of years past
 In time Mackinac Island's base was cast
 It's guessed hundreds of million years ago
 Where Mackinac Island is now aglow

 Inland seas dominated the landscape
 Lying smooth as if they were a pancake
 The gentle drift would make the seas briny
 Then periods of the sun so shiny

 Dried up the water in the coastal seas
 Soon piles made with help of the gentle breeze
 This act continued over untold time
 Leaving a great deal of salt at it's prime

 But soon enough mineral silt floats in
 Allowing a new process to begin
 Clay was formed which turned to shales
 As ground up shells spread around pushed by gales

 Past being left by creatures of the sea
 Pressure of sea formed limestone like a quay
 Riding on an under bed of old salts
 In time rock over it developed faults

 Which allowed circulating water through
 Washing out the salt to make something new
 Caverns which then collapsed as years went by
 The limestone fell into stacks some piled high

 The circulating water went to work
 They built what may be considered a quirk
 The water circled around the stacks
 Carrying debris, filling in the cracks,

 In time turned to cement, formed Breccia
 Rhymes with the end of Dyslexia
 Ten thousand years ago first appearance
 Of Island with Glacier's disappearance

 This could be when arch was formed by the waves
 Wore away lower sections same as caves
 For about six thousand years past the ice
 There mostly were High waters over Gneiss

 But don't take that for Granted. You will see
 With the ice gone there was a rising sea
 Open outlet was at high water mark
 Through the Mississippi. Could float an ark.

 This was the time most erosion took place.
 Hundred miles off was a Beucoux de glace.
 Oui! To the East-South East a Glacier sat
 Huge waves would hit the east side with a Splat!

 Tearing away the rock and leaving bluffs
 With quite a bit of help from the wind's huffs
 Wind and waves moved gravel like a snow flake
 Leaving little loose on East side in it's wake

 Maybe couldn't find your way out of the woods,
 If lost going to Grandma's house with goods,
 By looking for moss on the tree's North side
 But if you checked where gravel likes to hide

 The flow might tell you which way is the east
 Or it would give you things to do at least
 Arches of Breccia are rare indeed
 It seems anyone who gave it a heed

 Since there was anyone there to see it
 Figured it would fall with the slightest hit
 It's very existence was a riddle
 It would cause the Ancient folk to diddle

 They determined it's a power center
 Maybe a door that man should not enter
 There were three main depths of the ancient lake
 The shores left made Isle look like wedding cake

 Lake Chicago and Lake Algonquin merged
 All but Sugarloaf and Fort Holmes submerged
 Fort Holmes is labeled as Ancient Island
 With ice gone land raised up to be high land

 Fort Holmes was likely storm waves farthest reach
 The huge waves thus widened Sugarloaf's breech
 Wore away much with the help of gravel
 Ate more Breccia then Glacier's travel

 Which perhaps had thousands foot high shoulders
 The Signs are a few non-limestone Boulders
 Land rose and through Port Huron lake ran out
 Many floods appeared as did times of drought

 The water rose to form Nipissing lake.
 In that time one could expect an Earth quake
 Crack-in-the-Island likely formed that way
 Because of the process back in the day

 The land was rebounding from being quashed
 Lava flowing in the Globe had been squashed
 Ice was heavier farther you look north
 You'll find more rising land as you go forth

 This mainly is what caused outlets to close
 And the main factor in the land's transpose
 Another legend about the Island
 Is it was turtle, must be the highland

 Once a headland connected to the south
 Lake water ran out maybe helped by droughts
 But mainly a low outlet was about
 Would have been a south east bound route

 Then a river ran north around our isle
 Into a water fall that ran a while
 Hundred feet tall too much for fish that spawn
 That seems to been there since the Ice was gone

 Then was lost by the lake's repeated rise
 Here's something else that may be a surprise
 It appears the climate was not as cold
 Six Thousand years past I say being bold

 After all the Glaciers had receded
 The temperatures all rose unheeded
 But then Temps came down to today's level
 That and high tides ancient folk didn't revel

 Last four thousand years storms have come from west
 Building up Isle as if it was it's quest
 North is coastal drift or littoral drift
 Island building there with help of uplift
