In an earlier post, we told you about U.S. Geological Survey (USGS)’s launch of US Topo – free (!) online topographic maps that can be downloaded and printed at the USGS Store. Created in the familiar 7.5-minute quadrangle format like the legacy paper maps, US Topo maps are supported by frequent updating (3 year cycles) and feature on-screen geographic analysis. For those new to these digital maps, USGS now offers a video tutorial on using US Topo, the GeoPDF functionality and Terrago tools available for use with their GeoPDFs. The USGS Map store has free downloads of all the topographic maps ever produced by the USGS, including historic maps. Take advantage of these free tools and maps and be prepared when going into the backcountry. Live to ski another day!
