Following datasheet directions we hiked 2.5 miles north from the gate at the Bayocean parking lot, and then west on a game trail to the top of a high dune just a few hundred feet away. In 1975 the dune was still described as being covered with short vegetation. Now the trees and brush are so thick that I’d hiked past it many times without knowing it was there. When Eleanor found Reference Mark No. 3 (another bronze disc) near the end of the trail at the top, we knew we were close. We had to do a little bushwhacking, but nothing like that required to reach Bayocean’s highest point. An orange, plastic witness post stood out from the greenery, but that was different than described in the last datasheet update, and the station disc was not two feet east of it, so that threw us off for a bit. But after clearing a circle all the way around the the post we found the disc two feet north of it.
Why was it there? David Moore, a surveyor from Albany, Oregon, said stations like this were set up all along the coast, and for miles inland, after average sea levels were determined in 1927. They were used by land surveyors to calibrate their equipment for elevation, after checking for updates. Though latitude and longitude were added to the datasheets, surveyors used other monuments to calibrate for that. This dune was an obvious choice for a station because it was high and stable. A hydro signal originally placed next to it must have have been visible from Tillamook Bay before trees obstructed its view.
