We present Chandra observations of hot gas structures, characteristic of gasstripping during infall, in the Virgo cluster elliptical galaxy M60 (NGC4649)located $1$ Mpc east of M87. $0.5-2$ keV Chandra X-ray images show a sharpleading edge in the surface brightness $12.4 \pm 0.1$ kpc north and west of thegalaxy center in the direction of M87 characteristic of a merger cold front dueto M60's motion through the Virgo ICM. We measured a temperature of $1.00 \pm0.02$ keV for abundance $0.5 Z_\odot$ inside the edge and$1.37^{+0.35}_{-0.19}$ keV for abundance $0.1 Z_\odot$ in the Virgo ICM freestream region. We find that the observed jump in surface brightness yields adensity ratio of $6.44^{+1.04}_{-0.67}$ between gas inside the edge and in thecluster free stream region. If the edge is a cold front due solely to theinfall of M60 in the direction of M87, we find a pressure ratio of$4.7^{+1.7}_{-1.4}$ and Mach number $1.7 \pm 0.3$. For 1.37 keV Virgo gas wefind a total infall velocity for M60 of $1030 \pm 180$ kms$^{-1}$. We calculatethe motion in the plane of the sky to be $1012^{+183}_{-192}$ km$^{-1}$implying an inclination angle $\xi = 11 \pm 3$ degrees. Surface brightnessprofiles show the presence of a faint diffuse gaseous tail. We identifyfilamentary, gaseous wing structures caused by the galaxy's motion through theICM. The structure and dimensions of these wings are consistent withsimulations of Kelvin-Helmholtz instabilities as expected if the gas strippingis close to inviscid.
