When you go for a walk in the woods or go camping or hiking, you might see little marks on the trees or rocks. These marks are called "trail blazes". They help you stay on the path so you don't get lost in the forest or woods.
Each trail blaze is like a little signpost made of paint, plastic or metal that tells you which way to go. Trail blazes are usually colored brightly so they're easy to see. They might be red, blue, yellow, or even green.
Trail blazes are made by people called "trail builders". The trail builders mark the path with blazes so that people can find their way along the trail. It's like leaving breadcrumbs along a path for others to follow.
So, the next time you go for a walk in the woods, try to spot the trail blazes! They can help you stay on the path and have a safe and fun adventure in the great outdoors.
