CHICAGO ROCKS! Geology in the City
Daily Objectives #13 (February 23, 2010) J. Hemzacek and L. Sanders
assignment is due on Thursday!
By the end of today's class, you should be able to do the following:
w Review: Locate a given feature on each of three different maps:
- street map - topographic map - map of surficial geology.
w Using the "Index to Topographic Maps", determine the precise location of a topographic map on the geologic map.
(For example, in class, we worked with the Berwyn and Blue Island topo quadrangles.)
w Using the key to the geologic map, identify the geologic formations that occur in a specific area.
(For example, in class, we counted 7-8 geologic formations,
plus two special symbols, that occur within the area covered by
the Blue Island topo quadrangle.)
w Using a topographic quadrangle and geologic map together, determine where on the topo map a specific geologic deposit can be found.
(The example we did in class involved finding where the Parkland Sand
deposit could be found in the Blue Island topo quadrangle.)
