7599 13 Mar 1984 @ 1800 --- research-mab 3-13-84 Additional observations on Geyser Hill: the funnel shaped vent of “Inverted Geyser” east of Arrowhead Spring can not be found. It seems highly probable that it may have been destroyed by a violent rupture of the sinter sheet around 1m in diameter. Accurate measurements & a review of records on Inverted will be made later to test this theory.
No attachments for this geyser.
Baseline does not exist.
