This area in Centennial can be found with a short walk from the trailhead. At the trailhead follow the trail to the first small clearing, there will be an option to go left or stay right. Stay right. After crossing Centennial Stream you will go up a hill where you will find another crossroads. Here you must stay left and you will dip down towards the stream’s floodplain. Now you are in the hemlock forest. This is the oldest part of Centennial. It is also damp and home to many types of mushrooms photographed below. Other than the mushrooms, which are fungi, there are barely any herbaceous plants on the forest floor. The floor consists mostly of pine needles and dirt. The woody plants include Japanese Barberry, Hemlock, Eastern White Pine, and Yellow Birch.
