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.

Plan hikes and runs—and estimate just how good the views are going to be—with the new EPA Air Quality forecast maps in Gaia GPS. You can view current estimated levels of pollutants with the Air Quality (Current) overlay, or take a look at upcoming levels with the Air Quality (Tomorrow) overlay.
