Unformatted text preview: GY 301: Geomorphology Lab 3: Introduction to Topographic Maps; Coastal Geomorphology Page 1 of 5 Your Task: Today’s lab is your first opportunity to closely examine topographic maps. You will be asked to answer various questions about map format (e.g., scale, layout etc.), will be required to locate features using the most common grid systems (Township and Range; Mercator Grid System), and will also get a chance to interpret geomorphological features associated with coastal processes. Please note that the topographic maps you will be using come in different scales and that we don’t necessarily have a lot of copies of each map. For some maps, we only have 3 or 4 copies. When necessary, you will be provided with scanned portions of maps (e.g., today’s lab contains a scan of the Point Reyes, CA Quadrangle). Other times, you will have to share maps. The most common scale (1:24,000) will not easily fit on the small desks that we have in room 42 so it might be a good idea to push a couple of them together to form a larger table surface. Please put the desks back in rows when you are done. Outside of the normal lab session, maps are available in the storage cabinets in room 337. They are alphabetically sorted. Due Date: 5:00 PM Sept 11th PART I: SIMPLE MAP READING EXERCISES A) Refer to the Ontario, California topographic map and answer the following questions. Note, on this map, roads often follow section lines. 1) What is the RF of the map? ___________. What is the CI of the map? __________ [2 points] 2) Which direction is East Etiwanda Creek (sections 16 and 21), T1N, R6W flowing? (Compass direction please) _________________________ [2 points] 3) Which map sheet attaches to the northwest corner of the Ontario California map sheet? ________________________________________ [2 points] 4) What is located in the E½ of the NW¼ of section 27 T2N, R7W? ____________ [2 points] ....
