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.
