Sometimes in the United States private land won't be marked clearly or there won't fences along the lines or maybe there aren't no trespassing signs. Especially in the western parts with big open spaces this can be a problem.

Or sometimes the land can be public, but the rules can be different depending on the who owns the land and whether its say a Wilderness area or a National Forest.

What is the easiest way to tell who owns the land?
