the sand caves of loess hills

Here we go rockhounds tomorrow i will attempt to go to one of my first discoveries. While hiking trails one day my kids came across this little cave. It has a natural spring running through it. Its full of different rocks, agates, and clay. Hopefully all the rain lately hasn't made it too overgrown to get to the cave. But i do hope it has washed down some nice treasures. This place is also where i found my first peice of petrified wood. So wish me luck and i'll tell ya about it tomorrow.
