![]() ![]() While you’re scoping lines, don’t be afraid to add additional layers, like satellite maps (listed in layers as NAIP), shaded relief, and even Google’s Terrain map to get an even better feel of the terrain. (Not a substitute for actual snow safety training, but still helpful: Select a safe route.) Next, turn on “Slope Angle Shading.” (Find it on the left-hand panel under “Preset Layers,” below the map overlays.) This feature is uniquely beneficial in the wintertime: It color codes the terrain based on its steepness, making it easy to visualize both the most skiable slopes, as well as the most avalanche-prone ones. (Still don’t understand? Now’s a good time to learn to read a topo map.) You’ll see any preexisting trails, forest roads, and other routes that will help you move through the terrain better. These layers are based off the classic USGS quads and will help you visualize the terrain. Start with a base layer like the USGS or FSTopo maps (on the left-hand side of the screen). Like a paper map, but better (c/o CalTopo) It involves more than drawing a line on a map, and there is a learning curve, but master CalTopo and we bet it’ll set you up for a more successful trip-and maybe even help you find some hidden powder stashes from your couch. Our favorite (free) web-based app for planning backcountry ski trips is CalTopo. That’s good news for backcountry skiers because our whole discipline is “off-trail,” and maps are paramount to staying on-course and in safe zones. With today’s technology, you can not only find any map you want, but also analyze one with much greater detail and accuracy, alter it for your needs, and navigate with it in the field. Maps have come a long way since the days of pre-printed USGS quads and compass navigation.
