Preliminary Isostatic Residual Gravity Map of the Tremonton 30' x 60' Quadrangle, Box Elder & Cache Counties, Utah, and Franklin & Oneida Counties, Idaho (MP 14-2) Colorado River History -- The National GardenerBy: V. E. Langenheim, R. Q. Oaks, H. Willis, A. I. Hiscock, B. A. Chuchel, J. Rosario, and C. L. Hardwick A new isostatic residual gravity map of the Tremonton 30' x 60' quadrangle of Utah is based on compilation of preexisting data and new data collected by the Utah and U. S. Geological Surveys. Pronounced gravity lows occur over North Bay, northwest of Brigham City, and Malad and Blue Creek Valleys, indicating significant thickness of low density
