For those that don’t mind pulling out your phone in the backcountry...this photo was taken with an app called Theodolite ($5.99). You sight the bottom (or top) if the slope in the crosshairs, and the elevation angle reads out on the right. Also captures data like lat, long, azimuth and elevation. Pretty slick.

Two skiers were killed Saturday in an avalanche near Crested Butte while skiing across a slope of 37°. They were following a summer hiking route.  

I recently found an easy method to immediately assess slope angles while out sking at: http://poleclinometer.com
See image below of the sticker that goes on your ski pole. Must be sized to your pole diameter, but it's inexpensive and easy to use. Note that the angles pictured below are 27°--the upper limit of safe slope angles in avalanche terrain.
