| The QUINTESSENTIAL Alaska tour. Note the clear, mirror-smooth water, snow covered mountains and the BLUE ICE!! This occurs when snow falls on a glacier, is compressed, and becomes part of the glacier as it winds its way toward a body of water. During its travels, air bubbles that are trapped in the ice are squeezed out, and the size of the ice crystals increases, making it clear. Blue ice is much more dense and clear ice has begun to melt. |

Day Two, task one. Portage Glacier. A name first recorded in 1898 by Thomas Corwin Mendenhall of the U.S. Coast and Geodetic Survey, so called because it is on a portage route between Prince William Sound and Turnagain Arm. Hundreds of years ago the glacier filled the entire Portage Valley (14 miles), and was connected to what are now five separate glaciers. It is currently 6 miles long and has its terminus at a glacial lake, self created. 
Homage to Abbey Road
