Here's a quick and dirty trick for estimating elevation I learn in an astronomy club. I'm pretty average so it works great for me.
Extend your arm position your hand facing back at you. On average, supposedly, each finger width represents 2 degrees. Hence each hand span, including thumb, is 10 degrees.
I use this method all the time and I am usually pretty close.
