  route: From the just east of the Big Rock Ridge Summit, follow the large ridge that goes south-southwest a half mile. Before it reaches a level section with a few trees on the ridgetop, traverse east 0.1 mile and follow a smaller ridge down about 0.2 mile. Follow a deer track to the creek on the east side of this ridge.

  route: a simple but exhausting route is to go to the Big Rock Ridge summit and follow the largest ridge southwest from it (that would be on the left as you fast southwest from the top). After passing a part of the ridge that has ups and downs and a few trees on the ridge, you will reach a steep descent with a conspicuous mudslide. Head right (west) just above the mudslide, and descend on a small partly grassy ridge somewhat near the stream that flows down from the mudslide until you find a rock outcrop close to the stream

  each creek flowing into this waterfall has another waterfall near enough to this that I'm using the same gps coordinates for all three. On the Tom Harrison map of Big Rock Ridge (2007), it's at L in Lucas Valley Preserve.

  route: From the Big Rock trailhead, follow the Big Rock trail 1.0 mile. When it passes under a few small oaks shortly after the switchback, head straight uphill. When you reach a ridge (in the middle of another group of oaks), find a deer track that traverses east just above the bushes. You should pass above a medium sized rock outcrop. Cross the creek on a deer trail at the top of a 10 foot waterfall that is somewhat hidden in bushes. The terrain is somewhat difficult here, but most other parts of the creek have steeper terrain with bushes. Traverse to the southeast until you reach the next ridge. Look for a field with some small rocks at the upper end. Head straight downhill through that field, and find a deer track at which to cross the creek. Follow the creek a short ways downhill and the waterfall will stop you.

  Just a few feet above the falls where streams converge. I normally classify waterfalls this close as one, but this one is hidden so that it's hard to see while looking at the main waterfall, and the presence of two creeks complicates the classification
