Here is a wonderful site to check out on Topo Maps!!!
I am currently teaching a Navigation Class (a 3 credit class) at my local community college.
While preparing for my class on topographic maps I came across this fine power point presentation from the "World of Teaching."
The power point presentation is FREE and provides a nice overview on topographic maps. This would be a nice intro for Scouts.
