One of the best examples
of formations caused by glaciers is the world famous Yosemite National Park. It
is located about three hundred miles North of Los Angeles, and about one
hundred and fifty miles East of Sacramento. Geologists believe that the
"U" shaped valley was created by the movement of a glacier, hundreds
of thousands of years ago. The more common, "V" shaped valleys, on
the other hand, are created by flowing streams.
Along with snow and ice,
glaciers contain debris and rocks, some of which are very large. As the glacier
moves through the valley, it scrapes against the walls. For this reason, the
walls of Yosemite valley are very smooth. The steep vertical sides of Yosemite
Valley create very beautiful waterfalls, some of which are the highest in the
world
