July 2009 Shoshone Geyser Basin Report

Trailside Geyser:    Active

 

Little Giant's side vents have enlarged and were having small wave like eruptions, while a noisy vent in the side of Little Giant steams and overflows, but Little Giant itself is completed placid.

 

Double Geyser has become a perpetual spouter of only a foot or two with constant heavy overflow down it's main runoff channel,  All surrounding areas are bone dry;  indicating no eruptions, as far as I can tell.

 

"Trio Geyser" was heard gurgling as I left the basin, but Meander and Locomotive showed no signs of life.

 

Soap Kettle is dormant with low water levels and dry catch basins

 

Gourd and Shield were active, but not frequently so.

Therefore, UNNG-Shoshone-11 was having impressive doming, heavy overflows, nice thumping, and bubble showers.

 

Minute Man Geyser active

 

Five Crater Hot spring:  active

 

Orion Group:  Sadly no change here, the water levels are as bad as ever. Although Union Geyser is making a nice base drum-like pounding sound. Steam was seen escaping from cracks at the base of the South cone, sad to see the cones deteriorating. 

 

Based on the thick bacteria mat, Taurus Spring has not had an eruption in a long time.

 

 

South Group:

 

 "Diverted Geyser" was trying to erupt, but could not. The 1994 blowout was having nice three foot eruptions, but "Rototiller Geyser" looked dormant.

 

North Group:

 

Bronze Geyser appears from the wash zone, and the deep runoff channels to still be having large eruptions; it looks like a lot of water is ejected.

 

Lion Geyser is dormant with standing water,

 

"Old Lion" was lightly splashing

 

"Snail" & Fissure were not seen erupting, but are probably active.

 

"Hydra" looked like it might be active, although no eruption was seen.

 

Velvet Spring is once again dormant, with occasional light boiling in the east/bottom vent only.

 

Bead Geyser: the platform was dry, so I was surprised by a single eruption in the afternoon, it quickly refilled, but no more eruptions were seen that day.

 

Knobby Geyser: is in constant overflow. Water is flowing into the collapsed area just above Knobby. A single, but long major was the only eruption seen all day. With all that overflow: "Slosh Geyser" was dormant".

 

P28, the double vents that took over the overflow function of Mangled Crater Spring are having nice small eruptions, and was even seen erupting when Mangled Crater was quiet.

 

Frill Spring:  had what looked like an aborted eruption. It had heavy sustained overflow with surge after surge for thirty minutes!  It then surprisingly just drained completely; Refill was slow over the course of the day, as if it had a full eruptive series. 

 

In the Lone Star Camp Group; 

 

Clamshell Geyser was active, but not much of anything else.
