By the end of today's class, you should be able to do the following:
The Mega-Mosaic, revisited
w (Continued from last time) Determine the locations of high land and low land for a select group of topographic quadrangles.
w (Continued from last time) Put together the information from the topographic quadrangles to complete a "mosaic" picture of topography in the area of interest.
w (Review) Use contours on a topographic map to find the location of stream valleys.
w (Review) Determine the direction of flow of a stream using contours on a topographic map.
w (Review) Sketch what a stream valley would look like on a topographic map.
w Find the "Map Locator" resource on the USGS web site, and use it to find and download topographic maps.
Putting It All Together
w Using topographic, geologic, and street maps, locate the position of the special study area identified during class.
w Describe the study area in terms of its topography and surficial geology.
w Generate hypotheses for the study area's formation
w List the steps you would take to investigate this study area on a field trip.
