As there is only now one natural bridge the park could be renamed in the singular, but perhaps some day the soft sandstone will wash away and there won't be any. Come out and bring your camera and get a picture of it while it's still there. It's pretty cool.
The cache contains a small ink pad and a little seahorse stamp, please do not take them, but use them to stamp your book.
Cache is just a little off trail and under some natural cover. Please keep it covered so it isn't mistaken for trash.
