OFVC Geyser Log for September 1-30, 2002.

Transcribed By Lynn Stephens


----------------------------------------------------------------------------
A Note on Intervals:

Intervals have been computed in cases where observations are for consecutive
eruptions.  In cases where observations are not known to be consecutive,
intervals have not been computed.

Intervals computed when both observations were "ie" are noted with a
preceding * (e.g. *2:16).
