[Geysers] Riverside's bimodality

[Jeffrey Cross]

Riverside Geyser is known to erupt at intervals of (currently, per Ralph's
posted data for 2005) every 6h04m or every 6h42m.  The two intervals occur
in a ratio of 2.3 to 1, favoring the short mode.

Has anybody watched Riverside to determine if before the long eruptions it
shows a disturbance at the 6-hour mark?

Has anybody ever timed the durations to see if they are longer following a
long interval?

I believe John Wegel studied Riverside years ago, but what happened to the
data he collected?
