Sunny spring days make us eager to hit the trails. But warm, dry conditions at the parking lot do not necessarily indicate that all the snow has melted out on the high mountain passes and deep into the woods up ahead. In this guide, you’ll learn how to use the FreshSat, Snow Depth, Snow Stations (Daily), and Weather Forecast layers in conjunction with other trusted resources to get a good sense of how much snow to expect on your next trip. Use these tools to help inform your route choice, as well as what gear, traction, and layers to bring.
Examine trail conditions from the comfort of your couch using two new satellite imagery maps. FreshSat – Cloud Free shows mostly cloudless terrain. FreshSat – Recent shows as up-to-date imagery as possible. Both maps use satellite data from the Landsat-8 and Sentinel-2 government satellites, and are updated at least every 14 days.
