First, let me tell you a story. Back in August 1947 there was a
ship wreck in the Strait of Juan de Fuca. It was a foggy night and
the cargo ship, 
"Diamond Knot" was
rammed by another ship. The Diamond Knot was returning from Alaska
with a huge cargo of canned salmon. By the next morning the ship
sank and is resting, silently, in 130 feet of water just off shore
from Tongue Point at the above coordinates.
Serious recreational SCUBA divers consider this to be the best
wreck dive in Washington and Oregon. Ask any serious diver if he's
heard of the Diamond Knot. The photo shows the last hours of the
ship. More on the ship can be found here
This is all a true story. Now let's embellish it a little to
make it interesting to geocachers.......
Captain Onemartini was skipper of the Diamond Knot and he
recorded that his ship went down 0.40 miles from the Tongue Point
reference monument which is a famous surveying point for the
International boundary with Canada. He had a bearing of 127 degrees
Magnetic to that shore monument. He used his sextant as a Pelorus
and determined this from sightings of fixed points onshore, then
plotted the results on his chart.
He claimed he had hidden some of his personal posessions along
with his valued gin on the grounds of Camp Hayden. Your first task
is to find the monument as its the starting point for your search.
It will be a stone pyramid that is close to the shore line with a
plaque on the seaward side. This is an easy task with your GPS and
the information given so far.
He mentioned that he had come across an old fire hydrant by
walking from the monument in a direction of 147 degrees Magnetic
for a distance of 0.185 miles. He rested, drank a little more gin
and then took off in another direction but his memory was fading a
little by this time because of gin poisoning, i.e., he was drunk!
He did remember that the number of bolts holding the hydrant to the
stand pipe, M was related to his next heading. Finally, after
thinking about it he remembered the formula: Magnetic heading in
degrees = 6.8 * M. He did remember that the distance to the cache
from the hydrant was 688 feet.
Your heading to the cache while standing 40 feet North of the
hydrant will be? (This spot was picked to get good GPS
readings).
By now you should be getting closer. You're looking for a
plastic one pint pill bottle hidden out of direct view. It contains
South Pacific coins & odds and ends plus a log.
Captain Onemartini didn't have GPS in those days. In his time,
the normal approach was to solve this with compass and pacing off
the steps taken. A difficult and inaccurate method in this terrain.
A better method is to put your GPS to work if you know how. It will
be much much easier. That's where you come in.
Comments: 
- All bearings are Magnetic. If you use TRUE headings, deviation
is East 19°.
- Units are statute miles and feet. 1 mile = 5,280 feet.
- GPS coverage will be problematic in spots...you need to work
around this and use judgement when needed. This is particularly
true in the growing season with leaves on the trees.
- A Compass gives an immediate sense of direction and helps
alot.
- This cache is intended to force you to think about using your
GPS in different ways and show off the sights of Salt Creek, Camp
Hayden and Tongue Point. The operators manual can help you in
projecting waypoints.
- Enjoy your visit. This is one of my favorite coastal areas
besides Cape Alava.
You'll notice the past military presence here as this was an
important coastal defense post at one time.
This is not an easy cache but don't give up. Plenty of chances
to make a calculation error. Send me an email for more clues if you
need them plus some pictures. The hint has helped alot of
people.
This is a good safe family cache that can be enjoyed along with
a picnic on a lazy afternoon. Have fun!
