Description

From Hildreth and Fierstein, 2003 [1] : “Snowy Mountain is a small andesite-dacite volcanic center that straddles the rangecrest northeast of the main Katmai cluster, separated by about 10 km from Mount Griggs. Snowy Mountain was named during the National Geographic Society expedition to Katmai in 1917 (Griggs, 1922 [2] , p. 131). The name chosen evidently reflected how impressed those explorers were with its extensive mantle of snow and ice as seen from upper Katmai River, which was their closest approach to the edifice. Rising to an elevation of 7,090 ft (2,161 m), Snowy Mountain remains today the source of 10 substantial glaciers. Because glacial ice still covers nearly 90 percent of the edifice, the principal rock exposures are limited to narrow ice-bounded arêtes at higher elevations and ice-scoured lava-flow benches at lower elevations.
“Activity began at about 200 ka, and infrequent eruptions have since taken place from two vents 4 km apart that built contiguous subedifices which extensively overlap in age [3] . Only the northeast vent has been active in the Holocene. Sector collapse of the hydrothermally weakened upper part of the northeast cone in the late Holocene produced a 22-square-km debris avalanche and left a 1.5-square-km amphitheater that was subsequently occupied by a blocky dacite lava dome. Many products of the southwest vent are olivine-bearing andesites (55-62 percent SiO2), whereas those of the northeast vent are largely pyroxene dacites (62-64 percent SiO2). Estimates of eruptive volume yield 8+/-2 cubic km for the northeastern edifice, 5 +/- 2 cubic km for the southwestern, and 13 +/- 4 cubic km for the Snowy Mountain center as a whole. Only half to two-thirds of this material remains in place on the glacially ravaged skeletal edifices today."
From Wood and Kienle, 1990 [4] : "An active fumarole field on the summit of the tallest peak has melted holes through the ice. A zone of active shallow-level seismicity beneath Snowy Mountain is probably a manifestation of a hydrothermal system. This, together with its youthful, undissected form, suggests that volcanism at Snowy Mountain is recent. But no historic activity has been reported."

Name Origin

"Snowy Mountain" was identified by R.F. Griggs in 1916 as "Princess Peak" and then, in 1919, as "Snowy Mountain", "because of the extensive glaciers nearby" (Orth, 1971).

Snowy Eruption Timeline

From Neal and others (2004): "In mid-September 2000, AVO received a pilot report of a steam plume emanating from a depression in the surface of the upper Aguchik Glacier about 3 mi (5 km) SE of the summit peaks of Snowy Mountain * * * According to the pilot, Kodiak Air Service owner Willy Hall, this was the first time in his many years flying the region that he had seen either the depression or the accompanying steam. Hall also reported a strong sulfur smell while in the vicinity.
"At AVO's request, NPS Unit Manager and pilot John Bundy photographed the area from the air on September 29 and again on October 8 [see fig. 4 in original text]. The anomalous depression is roughly circular in shape, several hundred meters in diameter, and marked by concentric, nested crevasses that enclose a steep-walled opening of unknown depth. The crevassed ice defining the depression slopes towards the hole with increasing severity until nearly vertical ice-walls define the opening, also roughly circular in shape. Based on crude estimates of crevasse scale, we estimate the opening to be about 15-30 m (60-100 ft) across. This feature occurs on a portion of the icefield that flows generally to the southeast with a slope of about 8°; meltwater from this glacier eventually
drains into Kukak Bay. Geographic coordinates first reported by Willy Hall are 58°17.69' N, 154°38.78' W, placing the hole at an elevation of about 975 m (3,200 ft).
"In Bundy's photos from both September 29 and October 8, a faint wisp of steam emerging from the orifice is visible. High winds and turbulence quickly dissipated the steam during the Bundy flights, but the original pilot report estimated the steam plume to rise 100-200 ft (30-60 m). Neither Bundy nor Hall observed other fumaroles in the area, including the nearby summit peaks of Snowy Mountain. Actively steaming fumaroles had been recorded at the highest Snowy peak in 1982 (Kienle and Swanson, 1983; Motyka and others, 1993), however, over the past several summers, USGS geologists Judy Fierstein and Wes Hildreth noted no sulfur smell or trace of fumarolic activity anywhere on the Snowy edifice.
" * * * Based on several lines of evidence, the depression, central orifice, and minor, transient steam plume appear to be new features. We are not able to locate a similar structure on air photos from 1984 nor on Landsat images from 6 September 1999. It is uncertain exactly when the feature developed or became visible, however, based on Hall's comments, it was likely sometime during
summer 2000. The gradual 'sag' towards the central orifice indicated by crevassing patterns suggests the depression developed slowly (perhaps over years?) rather than suddenly during a rapid deformation or melting event that would have produced steep ice walls (John Paskievitch, pers. comm. 2000). On the other hand, the feature is quite similar in appearance to the 'subsidence
bowl' that developed over eruptive vents at Vatnajokull, Iceland, in 1996.
"AVO detected no significant change in background seismicity in the area over the course of the year, arguing against an intrusive event or significant acceleration of hydrothermal activity. However, the southeast Snowy edifice is not well-captured within the Katmai area seismic net and very small events may have gone undetected (John Power, pers. comm. 2003). It is possible that
changes in the surface of the glacier - retreat or other mass balance changes - have allowed an older feature to become more prominent at the surface."

June 27, 2001

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]."

Ash Forecasting

Mathematical models developed by the USGS forecast various aspects of how a volcanic ash plume will interact with wind—where, how high, and how fast ash particles will be transported in the atmosphere, as well as where ash will fall out and accumulate on the ground. AVO runs these models when a volcano is restless by assuming a reasonable hypothetical eruption, to provide a pre-eruptive forecast of areas likely to be affected. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available.

Ashfall thickness forecast

The Ash3d model was developed by the USGS to forecast how a volcanic ash plume will interact with wind and where ash will fall out and accumulate on the ground. AVO runs these models twice daily when a volcano is restless by assuming a reasonable hypothetical eruption altitude and duration. The map shows the model results of ashfall thickness for areas that are likely to be affected, if one were to occur. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available, and these plots will be automatically updated. The National Weather Service Anchorage Forecast Office will issue the official ashfall warning product and post them at weather.gov/afc

Ashfall Start Time

This map shows the modeled estimate of the time it would take for ashfall to begin following an eruption. It corresponds to the ashfall thickness forecast map shown above. This map uses the start time of either the twice-daily hypothetical model runs (time shown in the legend) or the actual eruption start time (if one were to occur). In the case of an actual eruption, the National Weather Service Anchorage Forecast Office will issue the official ashfall warning product that includes the ashfall start time and post them at weather.gov/afc
