Crossing the Continental Divide - Part 1
Flying the Interstate Highway System
by John T. Kounis
Planning a trip across the country can be intimidating, especially if you live in an area dominated by green on the sectional chart (indicating altitudes below 2,000 ft.). The Denver Sectional Aeronautical Chart, on the other hand, has five colors: all shades of brown, indicating terrain up to 14,433 ft. Brown is also the predominant color on the Albuquerque, Salt Lake City, and Great Falls sectionals.
