We present CO(J=1-0) data of the high-latitude molecular cloud, MBM16. The cloud was mapped completely at 8.4' resolution, corresponding to 0.2 pc at the cloud's distance. In addition to MBM16, portions of two new high-latitude molecular clouds were identified in the northeast and the southeast regions of the map. A 97 x 97 grid resulted in 9409 spectra obtained with the Harvard Smithsonian Center for Astrophysics 1.2 meter millimeter-wave telescope. A data cube extending 6 deg x 6 deg in Galactic longitude and latitude and 41 km/s in velocity was created from the data. The data cube is visualized using software that generates images from a matrix of values, that allows integrating the signal over a range of velocities, and permits the spectrum at any position to be viewed in an interactive manner. Extended velocity "wings" were identified in the data cube in about a half-dozen regions. These wings are localized spatially and are not associated with the high-density molecular regions but appear to be situated in regions containing low-density gas. The wings are not associated with star formation and may be the result of turbulence.
