Caption:Labeled version of color enhanced image of snow stratigraphy within the Spurr summit melt pit (see other image in image database without labels). The snow cross section provides a stratigraphic record of the past couple decades. The bold dark layer halfway down as 1992 ash. Above this, there are roughly 14 layers - one for each winter between summer 1992 and 2005. Two thin layers are visible in 1992, perhaps due to snowfall between the August and September eruptions? 1990 and 1991 are also much more prominent than overlying years. This is likely ash from nearby Redoubt eruptions. Extrapolating downward in time (and considering the distance already slumped), the current water level is roughly near the snow layers from the 70's, perhaps even back to the level of the observed pit in the mid-60's. The melt pit/crater must have only filled back in completely with snow in the past decade or so.

Caption:View from the north into the summit crater of Redoubt Volcano. The 1990 lava dome is completely covered, including the persistent ice hole that has remained open (warm rock?, incipient fumarole?) since the crater re-filled with snow and ice. The 1965-68 dome remnant, which also had a small ice hole open is also covered.

Caption:Big Lake (middle distance) is a shallow fresh-water lake located within the tombolo that connects Northeast Point to the main body of St. Paul Island. The Polovina Hill cinder cone complex (on the horizon) dominates eastern St. Paul Island. One of the largest monogenetic centers on St. Paul, Polovina Hill is two kilometers in diameter at its base and rises 120 m above its surrounding lava shield.
