Explanation of columns:
No.      USGS internal identification number (Pat Hill number)
sect.    Section designation for subdivided surveys
Status   Current status of data; all data have been transferred to the National Geophysical Data Center (ngdc) - the ngdc identification code for the survey is given if known.
Type     Type codes: M = map coverage, M/R = widely-spaced (regional) map coverage, A = original data analog, D = original data digital, G = gridded data
Name     USGS identification name (Pat Hill name)
