Caption:Photo of the western flank of Mt. Cleveland. The very dark deposit that forks down the western side of the volcano is the largest of any of the 2001 lava flows extruded during the February to March eruptions that year. The view is to the east. The northern portion of the lava flow is observed to fork when it encounters the highest part of the newly formed volcaniclastic debris flow fan deposit that was created by the 2001 eruption. Erosion of the fan deposit is very evident in the photo creating a higher edge.

Caption:Another panoramic photo of the western flank of Mt. Cleveland. The very dark deposit that forks down the western side of the volcano is the largest of any of the 2001 lava flows extruded during the February to March eruptions that year. The view is to the east. The northern portion of the lava flow is observed to fork when it encounters the highest part of the newly formed volcaniclastic debris flow fan deposit that was created by the 2001 eruption. Erosion of the fan deposit is very evident in the panoramic creating a higher edge. The right edge of this panoramic has a view of an older lava flow of unknown age. It could be from either the 1987 or 1994 eruptions, but could be a different year.

Caption:Photo of the northwestern half of the volcaniclastic debris flow fan deposit created from the 2001 Mt. Cleveland eruption as observed from the Augusta D. The northern secondary fork of the main northern fork of the 2001 lava flow is visible in the photo as well. The steepening edge of the fan deposit is evident on the right side of the photo with the large eroded debris just above sea level. The large breadcrust bombs and lava blocks on the surface of the fan deposit are also observed.

Caption:Panoramic photo of the volcaniclastic debris flow fan deposit that was formed by the 2001 eruption. The panoramic covers the view from the southwest to the west-northwest. The photo was taken from on top of the central part of the fork in the northern portion of the largest 2001 lava flow on western flank of Mt. Cleveland. The a'a lava flow can be seen on the bottom of the photo. The location of the 2003 field camp is visible in the lower right part of the photo. The larger breadcrust bombs that make up part of the newly formed volcaniclastic debris flow fan deposit are observed on the surface of the deposit.

Caption:Panoramic photo of the volcaniclastic debris flow fan deposit that was formed by the 2001 eruption. The panoramic covers the view from the west to the northwest. The photo was taken from about half way up the central part of the fork in the northern portion of the largest 2001 lava flow on western flank of Mt. Cleveland. The a'a lava flow can be seen on the left and right edges of the photo. The location of the 2003 field camp is visible in the photo right of center. The larger breadcrust bombs that make up part of the newly formed volcaniclastic debris flow fan deposit are observed in the foreground and extend straight out to the west. The height of the breadcrust bombs in this area are likely the cause for the forking of the lava flow.

Caption:Panoramic photo of the northern fork of the western 2001 a'a lava flow from the February to March 2001 eruption of Mt. Cleveland. This portion of the lava flow forked again when it encountered the highest part of the volcaniclastic debris flow fan deposit that was also created by the 2001 eruption. Breadcrust bombs and large blocks of lava can be found on top of and within the fan deposit. The channel of the lava flow is also observed down the middle of the flow.

Caption:Photo taken from the northwestern part of the newly formed volcaniclastic debris flow fan deposit from the 2001 eruption looking toward the southeast at breadcrust bombs. The northern fork of the main 2001 lava flow is observed in the background with the gray and teal colored tent (2-man Mountain Hardware Trango for scale) to the lower right of center indicating the location of the camp. The location of the camp is where this northern fork reached the highest part of the fan deposit, and forked for a second time. On the upper portions of the lava flow there is some steaming observed almost in the channel of the lava flow. This is where some fumarolic activity is taking place from the seeping of rainwater into the cracks of the flow.

Caption:Photo of the exposed portion fo the southern flank and summit region of Mt. Carlisle as observed from the volcaniclastic debris flow fan deposit created from the 2001 Mt. Cleveland eruption. The photo was enhanced for better contrast to decrease the amount of haze. What appears to be steam from the summit is actually fractus clouds behind the volcano.

Caption:Photo of the northern secondary fork of main northern fork of the western 2001 a'a lava flow from the February to March 2001 eruption of Mt. Cleveland. The majority of the newly formed volcaniclastic debris flow fan deposit is also visible next to the lava flow with the camp located just to the right of center in the photo. The photo was taken from the beach on the northern side of the fan deposit. The majority of the material of the beach in the foreground is made up of redeposited material from the fan deposit due to wave erosion and transport. This beach had nearly tripled in size between the deposition of the fan in 2001 till 2003 when the photo was taken.

Caption:Photo of an eroded pinnacle at Cleveland on the northern side of the beach to the north of the newly formed volcaniclastic debris flow fan deposit. The pinnacle is made up of an undated lava. Jon Dehn in the foreground for scale (around 1.7 meters tall). When using photo comparisons between pre-eruption and post-eruption photos, this pinnacle marked the late-February 2001 coastal boundary of the beach. The side that Jon is walking on would have been the ocean in February 2001, while the right-center part of the photo (just to the right of the pinnacle) would have been the beach at that time. Since this beach has nearly tripled in size since 2001, the pinnacle is now fully landlocked.
