The downed giant. It had fallen across a creek and will, for the time, serve as a bridge.
It was sobering to see such a huge tree lying on the forest floor.
Here was our guide for the hike: Marcas Houtchings. He's a former employee of Congaree National Park, and now works for the City of Columbia Parks. He knew exactly where all of the big trees were located and how to get us there.
Toward the end of the hike, we used another downed tree to cross a gut, saving ourselves a little trail walking.
