We present results from a survey in the CO(1−0) line at 115 GHz of the Northern Galactic Hemisphere at latitudes above 45 degrees. Our goal was to find intermediate velocity molecular gas. We carried out these observations using the Arizona Radio Observatory 12-m millimeter-wave telescope atop Kitt Peak. This survey resulted in the detection of three previously unidentified Intermediate Velocity Molecular Clouds, nearly doubling the known population of these objects. We include an investigation of the composition of dust grains which comprise these objects in addition to an analysis of their neutral hydrogen content. We also present calculations of the cloud masses and comment on the likelihood that these objects are gravitationally unbound. Finally, we make suggestions for future observations and summarize our ideas on the nature of these objects.
