Which feature refers to former islands that were outlined by large willow trees before river channelization?

• A. Pond Creek
• B. Picnic Shelter
• C. Wellington Street Dam
• D. Weir

Answer: (B)

When rivers were redirected and channels were straightened, existing islands could disappear, but their edges are often left as telltale landscape clues. Large willow trees growing along the old island boundary would create a visible outline that marks where the island used to be. A picnic shelter is a land feature you’d expect to find on that former island site, reflecting how the old boundary is preserved in a park setting. The other options describe water-related structures or a watercourse, which don’t indicate the remembered edge of a former island marked by willow trees.
