We study a family of semi-ample divisors on the moduli space of n-pointed genus 0 curves given by higher-level conformal blocks. We derive formulae for their intersections with a basis of 1-cycles, show that they form a basis for the Sn -invariant Picard group, and generate a full-dimensional subcone of the Sn -invariant nef cone. We find their position in the nef cone and study their associated morphisms.
