Free Topo Maps of the US and Canada

If you have any use for topographic maps from the USGS, USFS, and Natural Resource Canada, check out Free Printable Topo Maps (http://www.digital-topo-maps.com/).

Getting the maps is easy. You just zoom in to your area of interest in "Map" view (which shows a road map), switch to "My Topo" view, and select the topo zoom level you want. Then click on either "Landscape" or "Portrait" next to "Print from your computer:" located below the map image. A new window will open containing your map. The map of Horseshoe Bend on the Sultan River shown below was captured by right-clicking on the map in this new window and selecting "Save image as..." from the drop-down menu. (Note: The real image measures 1800x1200 pixels and is much more detailed than Blogger's scaled-down view shown here.)



The "Hybrid" view button next to the "My Topo" button shows a satellite image with a road map overlay. Both "Map" and "Hybrid" appear to work for anywhere in the world but "My Topo" only displays results for the US and Canada.

For ease of reference, I have added the link to Free Printable Topo Maps to the "Resources for Prospectors" section of the right-hand sidebar.
