This photo shows the highway roadcut exposing a cross section of the channel levee. The levee is built from many small, fluid pāhoehoe overflows spilling from the channel over the rim, shown by the thin layers here. On the right side of the photo, the channel wall is visible. The channel wall is covered in a thin veneer of fluid lava that remained after the lava in the channel drained. USGS photo by M. Patrick.
