Mr. Nelson (Goobacks)
About
The boss at the South Park Center for Seismic Activity, Mr. Nelson works with Randy Marsh monitoring Mt. Evanston and analyzing rock samples. After the jobs at the Center for Seismic Activity dried up and were taken over by Futurians, he and Randy ended up as co-workers again at the U.S. Geological Survey, where Mr. Nelson still performs work as a geologist, though he is now presided over by the same Geological Survey Supervisor.
