Measurements of surface subsidence, San Manuel Mine, Pinal County, Ariz
Attention given to improvement of rapid and precise method of surveying large number of subsidence pins and cracks in surface terrain; photogrammetric methods were used as adjunct to triangulation subsidence surveying as well as in ordinary topographic work; maps of various kinds were prepared to show results obtained; computation of survey notes was programmed for electronic digital computer.
