remove that soil and let me know what you find or what you feel. At this point you might not be able to see the tunk but you may be able to feel it. You can also take the tree out of the nursery container to remove that surface soil without harming the tree. When you're done we will put it back. Disturbing the roots like this wont hurt the tree.From the best I can feel, I start feeling roots 2 inches down from the top of soil. Top soil is very lose.
