How steep are these slopes? - Page 2

post #31 of 34
I have two compasses that has built in clinometer, but most of the time I just use my phone instead, for android there's an app called "swiss army knife" which also have a few other handy features built in.

I have an app installed on my iPhone called Theodolite. I just realized I haven't used it since a much earlier version I had installed on an older iPhone. Back then I found it difficult to see the screen and use in the field, so gave up on it. Will give it another try. It measures slope angle and a bunch of other stuff.

 

Was doing a little urban hiking with the dogs yesterday and took some readings using the cheap clinometer mentioned in post #26. Most of the "steep" road sections I'm used to walking up measure at roughly 10 degrees. One that is very steep measured at 15 degrees. I think that's about as steep as any straight up-down, no switchback road pitch in San Francisco.

 

It's not uncommon to find stairs cut into the hills of a lot of residential sections. Surprisingly many of these measured roughly 35 degrees...

 

 

 

I acknowledge "steep" is relative per individual and situation. This ain't skiing. Just curious about some of the angles encountered in daily life. And it does make me daydream about this type of thing.  ;-)

 

Again, here's that slope converter/calculator ...  http://www.1728.org/gradient.htm

Another way to visualize slope is to think about a common 12/12 roof pitch. My house has a roof that is pitched at this angle on one side. The other side is a 6/12 pitch. I clean my own chimney and get to climb up on the 6/12 side. The 6/12 side (50% slope) feels like it would be a decent intermediate slope when standing on it. However, when I look down the 12/12 side, I know there is no way I could climb up if it is bare. Sure I could find some footing with snow on it but I would run a huge risk of the snow avalanching out from under me. Have I thought about skiing it... Yeah, but the landing would be too flat.

I found the following graphic in a post in another thread. Kinda puts things in perspective...
