Arc-shaped bluff that many interpret to be evidence of landsliding during a pre-1964 earthquake of unknown age. The Frank and Maxine Reed Family Staircase at this stop was built to accommodate pedestrian traffic over a steep bluff along West Twelfth Avenue which is made discontinuous by the bluff. There was no sliding on this feature in 1964.

The Four Seasons Apartments, Anchorage, Alaska
The Four Seasons Apartments in Anchorage was a six-story lift-slab reinforced concrete building which crashed to the ground during the earthquake. The building was under construction, but structurally completed, at the time of the earthquake.

Emily Reynolds watching sea otters through a spotting scope
Emily Reynolds, a graduate student, looks through a spotting scope. The student is watching sea otters in Kachemak Bay forage. USGS researchers spend hundreds of hours annually observing sea otter foraging behavior to document prey composition and energy recovery rates.
