|Just east of Juneau, Alaska is Lemon Creek Glacier. Lemon Creek Glacier lies at the head of a valley drained by Lemon Creek. It is said to have been named for John Lemon who was reported to have prospected and done some placer mining on this creek with James Hollywood in 1879, a year before Harris and Juneau made their discovery on Gold Creek. John Lemon was in the Cassiar and went to Sitka in 1880. There he joined the Edmond Bean party of prospectors which blazed the trail over Chilkoot Pass to the headwater of the Yukon in the summer of 1880.|
|Above you can see the crevassing or fracturing of the glacier as it slowly moves over a change in the elevation of the ground.||Nothing has been learned of Lemon following the return of that expedition to the headwaters of the Yukon. James C. Pullen claimed a homestead at the mouth of Lemon Creek in 1881 and other homesteaders followed.|
Above is a closeup view of a cravasse on a somewhat
level section of the glacier.
The photo to the left is looking down into the
the left is a pool of water that has melted on the top of the glacier.
The brown substance is glacial silt. This
photo covers an area about 1 yard wide.
This photo to the left shows the steep side walls
and flat floor of the valley that a glacier has passed through. This
is common of valley glaciers. The white in the middle of the photo
is another glacier.
This a view that shows a medial moraine. The brown line in the middle of the glacier is the moraine. In the drawing below you can see how debris is carried along as it is scraped from the land at the joining of two glaciers.
As a glacier moves
it picks up rocks and soil and carries this material along with its movement.
When a glacier melts it leaves behind the material is was carrying.
These deposits of gravel, sand, sediment, rocks and boulders are called
moraines. The front of a melting glacier will leave behind a curved
ridge of debris called a terminal moraine as shown
in the center of this photo. At the upper right corner you can see
another form of deposition called an outwash plain.

stream that is running on top
of the glacier.
