In this video I’l shine light on the often asked question, “what are the triangle signs at the tops of mountains?” Well, they’re called witness posts and they were used in surveying. In this video I’ll explain the hows and whys behind them.

This Guide Was Written by Cris Hazzard
Hi, I’m Cris Hazzard, aka Hiking Guy, a professional outdoors guide, hiking expert, and author based in Southern California. I created this website to share all the great hikes I do with everyone else out there. This site is different because it gives detailed directions that even the beginning hiker can follow. I also share what hiking gear works and doesn’t so you don’t waste money. I don’t do sponsored or promoted content; I share only the gear recommendations, hikes, and tips that I would with my family and friends. If you like the website and YouTube channel, please support these free guides (I couldn’t do it without folks like you!).
