A new paper map was released in March 2023.

Avalanche Inclinometer

Avy savvy backcountry skiers and riders know that three things count when it comes to the terrain’s influence on avalanches: the slope, the elevation, and the (compass) aspect. And Steve's Avalanche Inclinometer delivers all three. Sure, you can find plenty of inclinometers (also known as clinometers) that are designed for carpenters, but the Avalanche Inclinometer is meant for people who spend time in avalanche terrain.

Three things count when it comes to terrain:

  • The slope angle.
  • The elevation.
  • The compass aspect.

This information is displayed in BIG FONTS which are perfect for tired eyes in stormy (or too-bright-and-sunny) weather. And it doesn’t display a gaggle of tiny buttons and widgets to decipher when you should be skiing.

And the Avalanche Inclinometer can talk to you —so you, and your partners, can hear the slope angle without even looking at your phone.

With a tap of a button you can send your current location via email. The email includes gpx and kml waypoint files.

You may also be interested in the Avalanche Slope Ruler to measure the slope on printed maps.

Usage Tips

You can sight across a slope by holding your phone parallel to the slope, or you can sight up or down a slope by sighting along the long-edge of your phone like a gun-sight. (Through-the-camera sighting is nifty when the light is just right, but it often isn't.)

When you have your phone aligned with the slope, a single tap on the screen will lock the data so you can read it. The Avalanche Inclinometer will even speak to you as you’re measuring the steepness so you don’t need to look at the screen. And the big inclinometer dial changes colors based on the slope which provides instant feedback on how the steepness of the terrain is contributing to the likelihood of an avalanche.

After measuring the slope, you can tap a single button to share your current GPS location, the slope in degrees, and the elevation in feet or meters. The email includes kml and gpx waypoint files and a link that allows you to quickly see the location in any browser. You can enter the email address one time and the Avalanche Inclinometer will remember it for next time. Less typing; more skiing.

Bottom Line

The Avalanche Inclinometer isn’t free, but apps don’t grow on trees. It will cost you less than the cost of a beer at a typical ski resort—think of it as buying Steve a beer!

In addition to this app, it is important that you take an avy class, pay attention to the avalanche red flags, use good route finding techniques, and practice your avalanche rescue skills frequently.
