You have to remember that we entered thru the exit, or the end of the tunnel and walked toward the entrance or the beginning of the tunnel. Here I'm looking back to the end of the tunnel.
Mike and Kevin examine the "box" that is the entrance. If I took a photo looking straight up you'd see daylight. The stream is about 7 feet above our heads. The entrance is blocked by years of debris that floated down the stream. Today water seeps through this debris into the tunnel.
