Enjoy your trip down there and bring a headnet.
I found that there was a lot of dry, termite eaten wood on the ground that was easy to light up.
Did not see any large animals at all, a few fat marmots. :)
The only part that you have to be careful about is crossing the water on the photo titled Sierra Water Slide.
The water was not deep, but it was slick there and falling could mean a long painful slide down.
At the bottom of the slide/bowl, where the kids were using it as a swimming hole, you may have to get your feet wet or wack your way around the brush to get around to the other side.
Bottom of that bowl you head to the right.
You probably want to stay on the right/West side of the Creek.
The West side had more land between the Creek and the Valley walls for you to hike and make camp.
Careful at the Cascade, it is very windy there.
Hold on to your hat and don't get blow off the edge!
When you get back, post up a trip report to let me know what it is like there.
I might take the family back there this year.
