Stars and gas at high-negative line-of-sight velocities ( km/s) point toward a remarkable spatial and kinematic alignment within 10 (25 pc) of Sgr A*. Observations of gas in emission and absorption will be reviewed in combination with observations of circumstellar masers to yield a geometric model. Possible kinematic and dynamical solutions will be presented.
