In 1792 a young Lt. William Robert Broughton was ordered to explore the wild waters of the Columbia River by Captain George Vancouver. This point is the furthest point inland that Broughton reached. He camped on an island that is visible from this view point and made compass readings from the headland to the northeast, which he named Point Vancouver, and the mountain to the southeast which he named after the Admiral of the British fleet, Viscount Hood.
To locate the micro hidden here, start at the above coordinates. From here you can easily find some loggable benchmarks labeled TUNNEL. How many of them are here? Let this equal T.
Reading the info on the beaver board you can learn what month and day Broughton camped on the island. Let the number of the month equal M and the number of the day equal D.
The offset to the cache from the listed coordinates in feet is (T*M)-D.
The heading in degrees (true) is the number of feet times D.
