The following questions refer to the 100 Topographic Maps books. For each section of the lab write a brief paragraph that describes the general landscape setting AND answers the specific questions.

(1) Page 104, Mt. Rainier, Washington. Notice the extensive network of glaciers on Mt. Raineir. What does this tell you about the local climate of this high-elevation alpine area?

Locate Kautz Creek, that flows southwest away from Kautz Glacier in the southwestern portion of the map. What is the shape of the valley occupied by Kautz Creek?

What does this tell you about the geologic forces responsible for shaping this valley? What stream type is Kautz Creek?

What explains this type of stream, in relation to the glacial source of water and sediments at the head of the watershed?

(2) Page 57, Chief Mountain, Montana. Notice the many lakes in this high alpine landscape. How did many of these lakes--such as Iceberg Lake, Helen Lake, and Sue Lake--form?

Locate and describe a horn on this map. How would you describe the shape of the valley occupied by the Belly River?

(3) Page 25, Holy Cross, Colorado. Draw a topographic profile across the Lake Fork valley, extending from the top of Sugar Loaf Mountain perpendicularly across the valley to the 10,750’ contour line on the north side. (Be neat and exact--use the graph provided.)

How was this valley formed?

Do you think the valley bottom is bedrock or some kind of sediment?

If sediment where there, what kind would be present where your profile crosses the valley bottom?

What landscape clues are present that provide information on these sediment questions?

Explain the differences in the formation of Timberline and Turquoise Lakes.

(4) Page 67, Catskill, New York. This area was subjected to continental glaciation, with the maximum ice extent reached approximately 15,000 years ago. How would you describe the hills in the eastern part of this map (Cross Hill, Roundtop, Little Roundtop)?

What do they and other characteristics shown on the map indicate about the direction of ice flow?

(5) Page 52, Jackson, Michigan. This area is completely covered with a terminal moraine produced by continental glaciation.

How has this affected the local hydrology?

Name two kettles shown on the map.

How would you describe “Blue Ridge” in the northcentral portion of the map?
