In this talk I will report penetration capacitance and transport measurements of pentalayer rhombohedral graphene aligned to hexagonal boron nitride. We observe an unambiguous 1/3 fractional quantum anomalous Hall state, as well as thermodynamic evidence for a gapless extended quantum anomalous Hall state.
