1665 Garrot:
PASCO (start 4:54pm)
8:38pm – temperature deflected 1 degree above baseline.  Deflection lasted about 1 second.  Shown on both sensors.  No one was in garrot.  Not reproduced on the HT dataloggers at the edges of the garrot.

​Phone datalogger (start 7:35pm) – Data did not save.

​Geiger Counter (start 5:18pm)
9:25pm – spike in CPM from 11 to 34 while team was there.  Returned to baseline after a few minutes.  Actually began at 9:24pm and peaked at 9:25pm and fell back to 11 by 9:26pm.

​HT dataloggers

​Geiger Counter (start 4:04pm)
5:47pm – CPM spike from 10 to 29.  Team away at dinner.
7:06pm – CPM spike from 10 to 29.  Team away at dinner.
