This Activity is meant for Boy Scouts.

wool or yarn, not too brightly colored, cut into 1 foot lengths.

This is a good camp activity where there is a lot of terrain. It works well for 20 or less scouts to track one Sasquatch. If you have more scouts, have 2 Sasquatch go off in different directions and have 2 patrols track each one. Each Sasquatch should have a different color of fur.

A leader is Sasquatch (Bigfoot). He takes the wool and heads off into the woods while the rest of the troop is doing some other activity, possibly cleaning up after lunch. (He should take another person with him).
Along the trail, about every 20 yards or so, Sasquatch should drop a length of wool, or tie it to a bush, or cling it to a tree trunk or on a branch. At the end of the trail, he should find a somewhat secluded place to rest and wait for the patrols to follow the trail to him. Silence is not that important so he can chat with his buddy while waiting.

After Sasquatch has been gone for at least 15 minutes, the activity leader takes on the role of a nature scientist whose life work is to investigate Sasquatch sightings. He calls everyone together to explain that Sasquatch was recently sighted near camp and we believe he may still be in the area. Sasquatch fur is extremely rare and he will give out a handsome reward to anyone that can bring him some - a larger reward for more fur.
The scientist then shows what Sasquatch fur looks like and points out a sample hanging nearby (or two samples if using two Sasquatch).

The only rule to give the people is that when someone finds a piece of fur, he must immediately and loudly give his patrol yell. This tells his patrol leader to come to him to collect the fur and lets everyone else know where the trail was last seen. A patrol leader stealing another patrol 's fur would not be a good thing.

When the patrols finally reach the Sasquatch, they should escort him back to camp to present him to the scientist. Patrols are given rewards or points based on the amount of fur their members have collected.
