The Geophysics Laboratory at the University of Arizona has had a continuing interest in making and analyzing gravity measurements over the state for a variety of purposes. Gravity work has continued at an increasing level of activity since the last report of this sort made to the American Geophysical Union [Sumner, 1965]. Master's and doctoral theses have been completed on the Tucson area [Abuajamieh, 1966], in the Tucson basin [Davis, 1967], and near Nogales in the Ruby quadrangle [Hench, 1968]. Other academic gravity survey work is now underway in the Avra valley immediately west of Tucson, in Walnut Gulch near Tombstone, in the Sulfur Springs and San Pedro valleys, in the vicinity of the Tonto Forest Seismological Observatory near Payson, and in the Flagstaff area.
