We present 11 and 10 dimensional supergravity descriptions of N(velence)2 4-dimensionalblack holes. The problem is formulated in the context of type IIA string theory compactified on R~((3,1))XCY_(3). The black holes are bound states of D4-branes wrapped on 4-cycles and D0-branes. We reduce the problem to a set of differential equations which describe black hole solutions in the lowest derivative supergravity theory. We argue that the full space-time is inherently 10 (or 11) dimensional. We then proceed to solve these equations in the near-horizon regime, which we define using ideas of "geometrical transitions" - where localized branes are replaced by smooth flux.
