[Geysers] Grand Geyser - ten bursts?

[Richard/Marion Powell]

MA:
    I remember a GOSA "show and tell" a few years ago where Dave Goldberg 
presented a tape of eleven or more burst from Grand.
    Scott Bryan (1955) Geysers of Yellowstone, p. 74 mentions 11 bursts in 
an exceptional eruption in 1983.  Is this the eruption Goldberg recorded?
    J.S. Reinhart (1974) Geysers; Trans. American Geophysical Union, pp. 
1052-1062, states on page 1057 that "At Grand, the jets can be interrupted 
as many as twenty times".
    E. T. Allen and A. L. Gay (1935) Hot Springs of the Yellowstone National 
Park, p. 164, state "In a phenomenal eruption in July 1928, witnessed by the 
writers, there were 29 distinct outbursts, ..., the whole active period 
covering 33 minutes."
    G. D. Marler, (no date, but pre 1973), Inventory of Thermal Features, 
etc., USGS GD 73-018, transcripted from microfiche by Lynn Stephens for 
GOSA, indicated )p. 113) that the number of separate eruptions during an 
active phase ranged from "6 for a minimum, with 45 eruptions being the most 
observed to date".  Grand was dormant for "the rest of the year" following 
the 17 August 1959 Hebgen Lake Earthquake.  The next eruption was 19 Feb. 
1960, followed by 28 eruptions to the end of the year (Marler, p. 114).
    There's more of interest in the Marler report, but I digress.
