This week the chapter is Lines, the term I chose is Contour - a line used to follow the edges of forms and thus describes their outline. This picture is from our Trip to Hawaii in May 2009, specifically the island of Kauai. We took a slow plane ride around the island. The Western side is the Napali coast. This was where the opening scenes for the movie Jurassic Park was filmed. Seriously cragged coast. In this picture the surf has just slammed into the coastline and shows its outline with a natural contour line.
