Lowest outcrops of Bouse limestone in quad.
Pristine double-holed Coors can on active fan surface. Can is approximately 30-35 years old based on the dangerous opening.
Coarse, alluvial fan facies of the Lost Cabin beds...getting notable finer grained here and also showing more gentle dip...nearly flat.
River gravel at intermediate piedmont level. Above highest outcrops of Chemehuevi, well below highest Bullhead deposits.
Miocene 'craglomerate' under very thin veneer of Qay.
Surprisingly well rounded cobbles involved with Bouse shoreline deposits high on piedmont. Local lithologies only...volcanic and plutonic. No sed rocks.
Well rounded local cobbles overlying Bouse limestone and sandstone.
West-dipping backset beds below Bouse limestone. Suspected beach deposits. Local gravels, subangular.
Beautiful day in the desert.
Bouse tufa and sandstone 'rind' on upslope side of inselberg. Near the upper limit of Bouse outcrops in quad.
Miocene fanglomerate: lower unit is monomictic breccia in mud matrix
Highest tufa clast in the Quad. Associated with in situ tufa coating.
high-standing tufa reef
Exhumed Miocene fanglomerate overlain by thin patches of Q fan.
What is this thing?
good argillic soil
Lost Cabin beds (Tlc) overlain by two generations of Q fan
Lost Cabin beds.
Lost Cabin overlain by Q fan and Qch. Base of Qch at left sits on rounded, fluvial gravel. At right it overlies mainly trib gravel.
Lost Cabin beds on northern Newberry Mtn piedmont. Who knew?
Lost Cabin beds overlain by fan gravel and some river gravel
Lost Cabin beds looking quite chemehuevi-ish
Extensive exposure of the Lost Cabin beds
please, oh please be a tephra bed
Rippled self-portrait...love that waterproof camera
sand ripples in shallow water
Bass-eye view of the underwater mudcracks
Chemehuevi sediments separated from Lost Cabin beds by a basal gravel containing river gravels grading west into fan gravels
Colorado River sand / mud over Lost Cabin beds. Sequence truncated by fan gravel with moderate soil.
Qch/Qcw over Tlc
Fan over Chemehuevi-ish seds over river gravel and fan gravel over Lost Cabin beds.
Lower Sandy Wash, Lake Mohave area, Nevada
chemehuevi in niche in old fan interfingered to right (west) with younger fan
edge of bullhead paleochannel at lake level
plaster of bullhead sand on fanglomerate
edge of bullhead paleochannel with concave base
base of bullhead paleochannel
cross-strata in Bullhead dipping into lake
pour-over caused by big rhyolite dike
great view of ubiquitous gravel stripes on old fan surface. these things are everywhere in the quad
Highest bullhead in quad: 1408'
K. Springer checking out root traces in rhythmites in paleochannel.
Rhythmically bedded mud and sand in paleochanel fill near Cottonwood Cove.
Rhythmite sands are green.
check subsequent photo in this set that shows the teetering block having fallen apart...
The bulk of the overall precarious looking pile of rhythmites appears to occupy a paleochannel.
Lost Cabin beds
Lots of Tlc
Thought it was a fault, can't prove. More likely a paleosol on erosional topography.
same paleosol in the slopes up this wash.
The only three clasts I could find. Slightly worked...likely manuports.
paleosol on erosional topography.
Qch and abandoned (hanging) young fan remnant. Suspect deep incision of young fans driven by lateral migration of unregulated Colorado River.
Qch overlain by river gravel...need to spend more time in this area...lots of units in small space.
Beach front fan that rips through the Qch in this area. Wondering if blotches of fines are reworked and not interfingered river and fan.
Bulk of bluff is fan. Interbedded fan and river evident near field book. Qch or Qcw seds at base.
fan over Qch/Qcw, some interbedding going on. Interesting implications.
Fan over Chemehuevi over Bullhead
probably should return to this wash at an earlier time of day....
beach barrier lagoon...classic.
Abundant petrified wood in prominently oxidized beds of Tcb...yellow.
River gravel at top grades laterally with mud and sand. Overlies prominent yellow bed of Tcb; Tcb overlies Tlc which look like Qch but is not.
Great example of interbedded Qch (Qcw?) and trib fans.
