Hat Creek Radio Observatory (HCRO) is a research facility used to study radio emission from space. The observatory has been here nearly half a century (since 1959). Hat Creek Valley is an ideal site for radio astronomy because of its relatively low levels of man-made radio interference. The observatory is surrounded by volcanic mountains that keep out terrestrial radio interference like television, radio and cellular phone transmissions.
