Further research...
Scheelite in the Boulder District, Colorado
Ogden Tweto
1947, Economic Geology (42) 47-59

1942, Eos, Transactions, American Geophysical Union (23) 49-56
Queen Creek, considered in this paper, is a typical large desert wash. It rises in the Pinal Mountains near the mining town of Superior and enters the outwash‐plain at Black Point about three miles north of Florence Junction (see Fig. 1). Thence it passes over the desert in a southwesterly...

Earth‐tides shown by fluctuations of water‐levels in wells in New Mexico and Iowa
T. W. Robinson
1939, Eos, Transactions, American Geophysical Union 656-665
It is quite generally known that ocean‐tides produce fluctuations of the water‐level in wells of the artesian type located close to the seashore by periodically changing the external load on the aquifer [see 1 of “References” at end of paper]. Fluctuations of ground‐water as a result of earth‐tides, however, are...
