  We present transport measurements of tunnel junctions made between Cu and
graphene in a magnetic field. We observe a transition to a Landau level like
structure at high fields, as well as a set of sharp features in the tunneling
spectra that shift with gate and tunnel probe voltage along the lines of
constant charge density. We explain the sharp features with the formation of
degeneracy split localized Landau levels, and addition of electrons to those
levels one by one. A large capacitive coupling to the tunnel probe also
increases the gate voltage spacing between the Landau levels.
