It’s big, it’s hairy, it’s smelly.

Those are the three classic indicators that you may just be looking at a Bigfoot, Yeti, Sasquatch, Wendigo or one of the other many variations on the theme.

But for many would-be Bigfoot hunters, it’s handy to know some of the less commonly known signs that you may be on the trail of the legendary beast.

1. Tracks. Typically 15 or more inches in length, pay close attention to the ground, even if it isn’t muddy or otherwise condusive to leaving prints. Sasquatch are estimated to be very heavy, and tracks have been observed even on dry, hard dirt. Also look for flattened grass alongside trails — they’ve been known to deviate from the path momentarily, according to Montana Bigfoot Project’s Brian Sullivan.

2. Structures. Whatever name you choose for the creature, they’ve been observed all over the U.S., and similar reports have been documented worldwide. One commonality is the presence of crude tree structures, generally arranged in a “tepee” pattern. Their use is a subject of debate within the Bigfooting world, with theories that they provide shelter, or perhaps are simply a territorial marker.

3. Sounds. Tree-knocks are one of the most commonly reported sounds when people have a Bigfoot encounter. One expert described them as “Babe Ruth smacking the hell out of a tree with a baseball bat.” The creatures have also been reported to mimic birdcalls and utter screeches and grunts.

4. The blur. You’ve seen the photos. As Kentucky Sasquatch Team founder Mike Cook put it recently, “Everyone in this room knows that Bigfoot is naturally blurry.”

5. Hoaxes. Don’t get tripped up by pranksters. Watch for classic fakes like tracks that are just too perfect. If someone is giving you a lead and their story includes portals and extraterrestrial activity, you may want to take their recommendation with a grain of salt.

With these techniques and a little perseverence, you might just be the next to catch a glimpse of the elusive Sasquatch. Happy hunting!
