Big Horn National Forest was the first place I visited on the western side of the country that really shocked me with it's beauty. Big Horn is located in the North Central area of Wyoming. I traveled along Route 16 in the Southern section of Big Horn. I like large rocks and rock outcroppings. I live in Northern Virginia and there aren't many large rock outcroppings here. Route 16 travels up and down and through valleys with some great views.
