OFVC Geyser Log for February 1 - March 11, 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).
