Take a close look at the detail in this chart. The terrain in northern Europe is very rugged with numerous islands and rocks. Oslo lies at the top of two very large fjords, Oslo Fjorden & Bunnefjorden. The channel narrows at Drobak and then leads down to the North Sea. Attention to detail is critical, the more detail I add, the more impressive the piece becomes. The end result in this particular chart was simply stunning. Many painstaking hours went into this chart, however the end result was more than worth it.
