Measuring Sun Exposure

One of the important route planning skills for skiing is timing.  In the winter we time for weather like wind so we can hit a run before the wind effects the snow. In spring however we time for sun exposure.  Getting to the top of a run just prior to the sun hitting the slope so we can time the corn cycle. Even more important making sure we descend at the end of the day before the sun goes off the slope and turns the run into a scary icy slope are critical route planning objectives. Below is a little tutorial on how with you can find out when the sun will hit.
