Abstract
In this paper we study the degeneration of a Galois cover of degree above a proper and smooth curve over a complete discrete valuation ring of mixed characteristics . We exhibit geometric and combinatorial degeneration data which describe the geometry of the special fiber of a minimal semi-stable model of .
