A GLACIER HOMEPAGE
Glaciers come and glaciers go,
Sometimes fast and sometimes slow.
Much is known about how they flow,
But some things we may never know.
Pre-Bull Lake, Bull Lake and Pinedale,
On leaving their mark glaciers didn't fail.
Granites, sandstones, volcanics and shale,
All have marks that tell a tale.
All glacial landforms I can't name,
But I'll say a few, just the same.
Kettles, drumlins, nunataks and kames,
And many varieties of moraines.
There are glaciers of many types,
Ice sheets and valley glaciers get all the hype.
Ice fields, ice caps, and ice shelves are a few,
Outlet, mountain, and rock glaciers exist, too.
The ice itself has scary things,
Of ice falls and crevasses no one dreams.
Moulins and ogives are also to be,
Growlers, bergy bits and icebergs are in the sea.
For glaciers Montana is a neat place,
Glacier National Park will give one a taste.
One-tenth of Earth's surface is covered with ice,
Will this increase or decrease as time goes by?
The Earth's position relative to the sun,
Helps determine when glaciers will come.
The next ice age we may not see,
But that it will come is a guarantee!
