David A. Hastings wrote in "The Geographic Information Systems: GRASS
HOWTO" (Nov. 1997) the following description on p. 10:

"The Spearfish data base covers two 7.5 minute topographic sheets in
the northern Black Hills
of South Dakota, USA. It is in the Universal Transverse Mercator
Projection. It was
originally created by Larry Batten (now of the Environmental Systems
Research Institute's
office in Boulder, Colorado) while he was with the U. S. Geological
Survey's EROS Data
Center in South Dakota. The data base was enhanced by USA/CERL and cooperators."

So: Larry Batten , USGS EROS Data Center in South Dakota and USA/CERL
and cooperators.
