We study a family of semiample divisors on the moduli space $\bar{M} {0,n}$ that come from the theory of conformal blocks for the Lie algebra $sl n$ and level 1. The divisors we study are invariant under the action of $S n$ on $\bar{M} {0,n}$. We compute their classes and prove that they generate extremal rays in the cone of symmetric nef divisors
