Oregon Vacation (10) Last Day
By the time I finished my Oregon City tour, I'm 22 miles from the Portland International Airport and I have 8 hours remaining before scheduled flight departure. There are still places worth visiting.
Portland's Highest Point
Council Crest Park is the highest point in Portland at 327-meter elevation. It is also the location of Portland's oldest geocache, hidden in February 2001.

The park was easy to locate. The geocache, on the other hand, was difficult for me. Its location is specified as a vector offset from the hilltop, at "185 meters in the direction of 285° from magnetic north". I've seen "magnetic north" once and looked up some scientific references, but I don't know a practical way to convert magnetic north to true north that is accepted in mobile apps.
