Question
llbrur uver Glacier le were extensively National glaciated by alpine glaciers dur Fly to Point 1. In what kind of glacial landform is this lake found? 2. (a) Fly to Point 2. What kind of glacial landform is shown here? (b) Fly to Point 3. What might explain why this valley enters the valley of Lake Sherburne closer to the present level of the lake than the valley marked by Point 2? 3. (a Fly to Point 4. What kind of glacial landform is shown here? (b) How does this kind of glacial feature develop? Fly to Point 5 along the eastern side of the Sierra Nevada Mountains in California. This view shows large lateral moraines at the bottom of Lee Vining Canyon. During the Pleis- tocene, glaciers flowed to the east through Lee Vining Canyon from the crest of the Si- erra down into the Mono Lake basin. Notice that there is a pair of moraines on each side of the canyon (this area is also shown in Maps T-13 and T-23a). Point 6 marks the crest of one of the inner moraines formed by a different glacial advance during the Pleistocene than those that left the moraines marked by Point 5 (a) Which moraine formed first, the one marked Point 5 or Point 6? 4. (b) How do you know? How deep (thick) was the ice in the glacier that formed the lateral moraines at Point 5? You may assume that the ice reached the top of this lateral moraine. (c) How much deeper was the glacier that left the moraines marked by Point 5 than those marked by Point 6? (Compare the moraine heights at the same place in the valley.) (d) y to Point 7 in the Tracy Arm fjord in Alaska. Compare the location of the South Sawyer glacier's terminus shown in Map T-14 (mapped in 1960) to that shown in the latest Google Earth imagery. Using the "ruler" function in Google EarthTM or the graphic map scale in the front of the Lab Manual, estimate how far the glacier has retreated. 5. FlExplanation / Answer
1) The cirque type of glacial landforms. It is because when depression occurs, the lake is formed.
The cirque type of glacial landforms are erosional landforms because huge snow accumulate and then moved throughly left depression.
2)
a. This is valley steep type of glacial landforms.
b. The valley at point 3 is U-shaped Valley which is gentle from both sides. Where as at point 2, the shape is steep which is why point 3 is cutting from both sides very easily than at point 2.
3)
a. It is horn type of glacial landforms. It is erosional type of ladform because it is made up of cutting the aretes.
Arete is made up two adjacent glacier.
b. This type of features are developed when glacier is eroding away.
4)
a. The lateral moraines form first which is shown as a point 5.
b. The point 6 is the medial moraines which is formed when two glacier meets but at point 5, the lateral moraines are formed form the debris which are released from the glaciers.
