Imbriani 1 Alex Imbriani Ho Seop Cha GGP115 2/18/2024 Mount Rainier, Washington 1. What drainage pattern is formed on Mount Rainier? Mt. Rainier exhibits radial drainage, where streams radiate outward from a central point. Lake Wales, Florida 2. What drainage pattern dominates this area? The drainage pattern observed in this area suggests a deranged drainage system, characterized by numerous lakes interconnected by rivers. Strasburg, Virginia 3. (a) What drainage pattern occurs in this region? (b) What do the erosional patterns of the channels indicate about the relative resistance of the ridges and valleys? a The valleys in this area cause a trellis drainage pattern. b Ridge feature significantly more resistant material than valley streams which meander through softer rocks whereas rigdes are straight and parallel streams St. Paul, Arkansas 4. (a) What is the drainage pattern in this area? (b) Qualitatively describe the drainage density in this area (i.e., does it look like it is relatively dense, or not very dense at all). a The drainage pattern on Mount Rainier is a radial pattern. b Hignt density Bright Angel, Arizona 5. (a) What drainage pattern occurs on the Kaibab Plateau? (b) What drainage pattern dominates in Bright Angel Canyon specifically? a this area has a rectangular drainage pattern.
Imbriani 2 b Trellis appears to be the dendritic drainage pattern in Bright Angel Canyon. Brandon, Vermont 6. (a) What is the fluvial landform represented by the wetlands along either side of Otter Creek? (Look for the green tree symbol to the left of Brandon, indicating the Brandon Swamp) (b) What fluvial landform probably separates these wetlands from the river? a Natural Levee b Ennis, Montana Ennis, Montana 7. (a) What type of channel pattern (i.e., straight, braided, meandering) does the main channel of the Madison River exhibit? (not the small, secondary stream) (b) The Cedar Creek Alluvial Fan represents a large deposit of material transported from the local mountains. How could this alluvial fan be affecting the Madison River channel pattern? a The channel pattern appears to be braided. b This alluvial fan could be affecting the river by adding more sediment to the waterway. This can cause build-up that restricts the waterway and/or could redirect water flow. This also increases the possibility of flooding. Guadalupe Peak, Texas 8. (a) What geomorphic name would you apply to Salt Lake? (b) What is the gently sloping area linking Salt Basin and Crow Flats to the Guadalupe Mountains? a Playa b Piedmont Menan Buttes, Idaho Menan Buttes, Idaho 9. What is the fluvial landform represented by the crescent shaped sand mounds along the inside of the meander bends of the river (found to the left of Menan Butte)? Point bars
