Snowy reported activity




Eruption Name : Snowy 2001/6

Start:June 27, 2001 Observed

Fumarolic or hydrothermal activity: BibCard
Steam: BibCard
Eruption Type:Not an eruption.

Description: McGimsey and others (2004) summarize this event as follows: "On June 27, 2001, Willie Hall of Kodiak Air Service called to report his observations of the 'steaming hole' in the glacier midway down the south flank of Snowy Mountain. Mr. Hall was the source for the first observations of the steaming hole in September, 2000 (Neal and others, 2004) [see figs. 4 and 5 in original text]. Hall reported that he flew over the area in late May/early June, 2001 using the coordinates previously established and could find no evidence of the hole. Keith Echelmeyer (UAF/GI glaciologist) conducted airborne glacier surveying in the Katmai region in early May and he, too, used the coordinates to examine the area where the hole was reported. He observed that the hole was still there, but 'not a big deal * * * not steaming and mostly snow-filled' [see fig. 6 in original text].

"Hall also reported that he noticed a recent change at the snout of the glacier that contained the hole, where the melt water stream emerges. For the past 5 to 6 years, the stream emerged from the glacier through a large tunnel (which he likened to a railroad tunnel). This year, the tunnel is gone (presumably collapsed) and melt water emerges from multiple small portals spread out along the face of the ice terminus. Hall suggested that the water had been warmer in previous years.

"In a follow-up report (Jan. 30, 2002), Hall said that later in the summer of 2001, while on one of his almost daily flights over the Snowy Mountain area, he noticed that the hole (vent) was indeed still active [steaming]."
