In this paper we construct a detailed map from pure and mixed half-BPS statesof the D1-D5 system to half-BPS solutions of type IIB supergravity. Using thismap, we can see how gravity arises through coarse graining microstates, and wecan explicitly confirm the microscopic description of conical defect metrics,the M=0 BTZ black hole and of small black rings. We find that the entropyassociated to the natural geometric stretched horizon typically exceeds that ofthe mixed state from which the geometry was obtained.Comment: 25 pages; v2: references adde
