Japanese Tunnel and Trenches SE of Mount High West [????- ]

A fairly large complex with 2 exits, several turns and chambers. It's very easy to reach from the main path leading up to Mount High West. Turn left right before the first major stairs begin to ascend up the mountain. You will walk West and come across it to the right of the path after a very short walk on the well trodden ribbon trail. There's also a trench system S of the Tunnel.
