The southern end of the Funeral Mountains, between Death Valley and Death Valley Junction in southeastern California, is accessed by walking on a large alluvial fan (fanglomerate) northward from Rt. 190. The succession in this region consists of Proterozoic to Mississippian marine sedimentary rocks, overlain by Cenozoic nonmarine sedimentary rocks.
Above: Bat Mountain, at the southern end of the Funeral Mts. The Paleozoic section here is made up of Devonian-Mississippian sandstones & limestones. Looking ~N.
Above: “11240 Peak”, consisting of dark reddish-colored conglomerates of the Amargosa Valley Formation (Oligocene-Miocene, ~20-25 my). Looking NE.
Above: Geologists looking at the Tin Mountain Limestone (Kinderhookian Stage, lower Lower Mississippian) exposed on the western face of a small ridge just southeast of Bat Mountain (see map). Looking ~S.
What are the geologists looking at? See pic below.
Above: Large mudmound (bioherm) in the Tin Mountain Limestone. Much of the Tin Mountain Limestone here consists of crinoidal limestones.
Above: Southern end of Bat Mountain, including “Hill 2997” (small bump at left-center), with Kinderhookian limestones of the Tin Mountain Ls. Looking ~W.
Above: Geologist climbing a steep limestone cliff in the southern Funeral Mountains, collecting samples intended for isotope analysis. This is the lower Tin Mountain Limestone (unit t2 of McAllister, 1974, USGS Bulletin 1386) (Kinderhookian Stage, lower Lower Mississippian).
