Also went back to the super steep ATV trail and remembered to turn on the angle meter this time.
Averaging the up and down readings, the angle of the road to the horizon is 30 degrees. Looking at the chart at Wiki indicates 30 degrees is equivalent to a nearly 58% grade. This is definitely the steepest trail I've been on and I'm not going to go on anything steeper. But it's also a data point. As I'm building and clearing new trails, if I stay under a 30 degree climb, I'm good to go. I'm thinking of making a jig out of plastic pipe with a plumb bob or 2 on it, and markings corresponding to 20, 25 and 30 degrees. Then I can evaluate slopes for possible trails and plan accordingly. My preference would be for no trails to exceed a 40% grade (around 22 degrees) but the 8 degree cushion is there if moving dirt to get the angle better becomes onerous. S
And suffice to say, no one will ever take a car up that 30 degree slope, even if the trail was wide enough.

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
