  In this letter, we propose a local detection scheme for the Majorana zero
mode (MZM) carried by a vison in Kitaev's chiral spin liquid (CSL) using
scanning tunneling microscopy (STM). The STM introduces a single Majorana into
the system through hole/charge injection and the Majorana interacts with the
MZM to form a stable composite object. We derive the exact analytical
expression of single-hole Green's function in the Mott insulating limit of
Kitaev's model and show that the differential conductance has split peaks, as a
consequence of resonant tunneling through the vison-hole composite. The peak
splitting scales with the binding energy of vison-hole composite, which is
comparable to the Majorana gap in CSL, well within the reach of experimental
observation.
