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.

Topographic Maps

  (Review)  Use contours on a topographic map to find the location of stream valleys.

  (Review)  Determine the direction of flow of a stream using contours on a topographic map.

  (Review)  Sketch what a stream valley would look like on a topographic map. 

  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.
