The Howell quadrangle is located in northwestern Utah, north of the eastern arm of the Great Salt Lake and about 8 miles south of the Idaho-Utah border. Part of the western Blue Springs Hills is exposed within this quadrangle. The Blue Springs Hills are a north-trending, low-relief mountain range in the northeastern Basin and Range Province. In this range, marine sedimentary rocks of the late Paleozoic Oquirrh basin and clastic Mississippian rocks crop out; rocks older than Mississippian in age are not exposed at the surface. The rocks were folded and thrusted, probably during Mesozoic time. Cenozoic high-and low-angle faults have modified the Mesozoic structures.
