Glaciers Topographic Map Lab Assignment

Make sure you have read the textbook and watched the videos.  You will use two topographic maps below.  The Mt. Tom topographic map is from Sierra Nevada mountain range in California. Valley glaciers carved the topography.  The Kingston, Rhode Island topographic map shows features that were formed by a large continental glacier in the last ice age.
