O Holey Night

H I self-absorption (HISA) features come in many shapes and sizes, but some appear similar to point sources (point sinks?) in the CGPS, suggesting they are unresolved at the 1-arcminute scale. An automated means of identifying these dark HISA "globules" in the H I data will be presented. The physical properties, spatial distribution, and interstellar medium context of the detected population will be discussed.
