that's very interesting, thanks for the summary!
"My opinion is that there are many small deposits of “black” nuggets scattered around several areas in SoCal here, most often covered with sand, but occasionally uncovered."
years ago when i was a kid, i remember an old timer had a theory about the peg leg nuggets. his grandfather had come out with the rush and 3 generations of his family supported themselves by gold mining. he taught me a lot about reading the hills. was kinda like eagle down's hermit pete, except he liked beer not wine
it was after high school and i got a job for the summer working in the garage at yosemite. one of the guys i worked with was my age and was born and raised in el portal. he introduced me to all the old timers down there. we used to sit on the wooden porch in front of the old el portal general store and drink beers with them. their stories were better than TV lol.
he said the "big blue lead" (the ancient tertiary river that provided most of the gold rush's placer gold) can be followed all the way from alaska to the tip of south america. he was sure that the big blue lead is the pishon river mentioned in the Bible. in Genesis chapter 2 it says: "10 A river flows out of Eden to water the garden, and from there it divides and becomes four branches. 11 The name of the first is Pishon; it is the one that flows around the whole land of Havilah, where there is gold; 12 and the gold of that land is good; bdellium and onyx stone are there." in those days the world was one continent. God split the continents when the world was covered with noah's flood. he said when baja split off from the mainland and tried to move north it was stopped by the gigantic granite batholith of the sierra nevadas. this caused uplift of the sierras. it also caused baja to rotate towards the west which stretched the land now covered by the desert southwest. it also rotated the transverse ranges 90 degrees so that they run east-west now, where originally they ran north-south like all of california's other ranges. during this 'stretching' the bed of the pishon river was split into many pieces were it crossed what is now the southern california desert. he said that when the flood waters receded and over the years since, the area eroded and the small chunks of the pishon's riverbed, which were cemented gravel and more resistant to erosion, became the tops of small buttes. eventually, most of the streambed overburden was eroded away leaving the gold exposed on tops of the small mesas. in conclusion he told me "the peg leg's deposit is one of those pieces of the pishon's riverbed, but the peg leg's deposit isn't the only one." he suggested that if im ever down there, to check the tops of all the small mesas i find.
i'd like to look for this one sometime... except, it seems wherever you look down there, either a ranger is pointing a gun at you or a plane is dropping a bomb on you...
