The oil- and gas-bearing strata, Mesaverde group and above, are nearly absent in the Rio Chama Watershed.
With this glacial stripping away of strata, the Mancos Shale, too, out-gassed, was crushed and flushed “from oil to soil”, and now recharges quality groundwater.
Drilling and fracking with toxins, carcinogens, and tracer radioisotopes dislodges more of same from substrata.
Neutron well-logging produces even more toxic and carcinogenic 239-Plutonium from fertile 238-Uranium (far right) in the Dakota Sandstone and Morrison Formation .
