Why the Maine Coast Is Smooth in the South and Jagged in the East
- South of Portland, Maine has long sandy beaches.
- East of it, the shore breaks into a maze of rocky headlands, narrow peninsulas and long thin islands.
- A NASA Earth Observatory feature explains that the line between the two was drawn partly by the rock beneath and partly by the ice that once sat on top of it.
