Other than the trail that is clearly marked leading to Mt. Lowe Campground, other splits in the trail reconnect to the trail until you reach the Junction with the Upper East Mt. Lowe Trail and the North Mt. Lowe Trail. Up goes to Mt. Lowe, down leads to Markham Saddle (though the sign says Mt. Wilson which is much further away).
