  We present a simulated cluster of galaxies, modeled with a pre-heated
intracluster medium, that exhibits X-ray features similar to the `cold fronts'
seen in Chandra observations. Mock observations at a particular epoch show
factor two discontinuities in X-ray temperature and factor four in surface
brightness on a spatial scale <= 100 kpc. Analysis of the cluster's dynamical
history reveals that the front is a transient contact discontinuity created by
an ongoing merger of two roughly equal mass subgroups. The cold front feature
in this realization is amplified by the adiabatic expansion of one of the
subgroups following its ablation from the center of its local dark matter
potential. The presence of cold front features in a cluster modeled without
radiative cooling or magnetic fields implies that such relatively complex
physics is not a necessary element of the phenomenon and suggests that the
prevalence of such features in high resolution X-ray images of clusters may
simply reflect the high frequency of ongoing mergers driven by gravity and
comparatively simple hydrodynamics.
