This past weekend I went on a 13 mile hike into the San Gabriel Mountains with my hiking group. Most hikers take the old roadbed to the bridge, but we decided to take the river bottom and come up to the bridge by way of the river below it. I have to admit this was a really great way to see the bridge for the first time. We also explored an old mine and checked out some waterfalls along the way. The mine is about 100 yards deep and has two tunnels that split off. One tunnel goes straight up and above the main tunnel and the other tunnel cuts to the left at the end of the main tunnel. Here is some information about the mine from the Los Angeles County Mine directory
