Keep the location of the clues and box a secret so the activity can remain fun for all.  Enjoy!

*****************************

LET'S BEGIN...

In this place of constant change
Between the river and the sea
Freshwater and saltwater meet
In the Yaquina ESTUARY.

To the west, in the distance,
The Yaquina Bridge shows
The location of the sea
From which saltwater flows.

From the east, past the marsh
The Yaquina River runs,
Bringing freshwater runoff
From inland mountains.

To begin, find the trail
Near a colorful sign (not white).
At the bottom of the post
A clue hides out of sight.

Write the letter that you find
In the square number one.
Now continue your Quest
And let’s have some fun!

Check out the small cove
Right next to the trailhead.
Is it filled with water now?
Or is it drained instead?

The semidiurnal tides
Of the mighty Pacific
Means water ebbs and flows
On a schedule quite specific.

 

DID YOU KNOW?

The Oregon coast experiences semidiurnal tides, which means we have two high tides and two low tides each day. The sea level rises over several hours (flood tide) until it reaches high tide, and then falls over several hours (ebb tide) until it reaches the low tide.

 

QUESTION FOR THE CURIOUS

Is the tide coming in or going out right now? How can you tell? Check your answer with the tide table in the Quest Box at the end of your journey.

 

Walk quietly down the path
Toward a pole as tall as a tree.
Sometimes ospreys nest on top.
What other birds do you see?

You may see Great blue herons,
Great egrets, gulls or ducks.
Many species migrate,
So their numbers are in flux.

On the wooden bridge
Tree swallows may be
Peeking out from nest boxes.
How many do you see?

Is there life down there
In the muddy, narrow trench?
What sounds can you hear
When you stop near the bench?

Check under the bench
For your next hidden clue.
Write the letter you find
In square number two.

This is the salt marsh.
Note the plants living below.
These are halophytes,
which means “salt-loving”, you know.

Jaumea, pickleweed
saltgrass, owl’s clover--
These plants do just fine
When the tide washes over.

At the end of the bridge
stands an evergreen tree.
It's a Sitka _ _ _ _ _ _ ;
its first letter is clue three.

This tree stands in the upland
So it skips a salty soak.
“Shake hands” to feel its needles.
But carefully -- they poke!

Unlike the plants of the marsh,
The plants here in the upland
Don’t need to be halophytic
Though they still must tolerate sand.

Ahead the trail divides, but
stay straight, careful readers.
Going left would lead to Hatfield's
buildings and bird feeders.

But before proceeding on,
Check the two pine trees.
Clue four is hiding low
Near the trunk of one of these.

Go forth; find a sign with terms
like "benthic" and "anadromous".
Does the second letter on the sign
Fit space five? Yes, it does!

Some species spend just
Part of their lives here.
But without this estuary
Their future would be unclear.

Lots of food, shallow water,
Plenty of hiding places -
Estuaries serve as “nurseries”.
We must protect these spaces.

At the next sign
You get a better view.
Eyes closed, take a breath.
What does the air smell like to you?

Check the sign. Clue six
of your mystery word
is the second letter in the name
of the crab-holding bird.

Are there bird outside today?
Are they flying? Are they still?
Do you see any birds
Holding food in their bill?

Birdwatching, crabbing, fishing -
This is a place for recreation.
Many people live here,
Others come on vacation.

Who makes a living
Here in the bay?
Try your hand at “I Spy”
What can you find today?

 

CHECK OFF ALL THAT YOU CAN SEE:

  • Channel marker (red triangle)
  • Liquid natural gas tank
  • Sailboat
  • Residential homes
  • Power boat
  • Oregon Coast Aquarium
  • Weather instruments
  • Someone fishing

 

After passing the brown wooden shelter,
The paving may come to an end.
Erosion reclaiming the path
Requires making amends.

A dynamic revetment
Has been placed along the shore
In an attempt to stop the sea
From taking any more.

 

QUESTION FOR THE CURIOUS 

What is a dynamic revetment? The answer is the in the Quest Box at the end of your journey!

The smooth river rocks
and snags chained in place
were brought here on purpose
to transform the space.

Turn around and go back to the shelter
Where a sign waits for you.
The seventh letter of its title
Is your seventh clue.

Though you now have all the letters,
They look a little strange.
To find out where to look next,
They must be rearranged:

3 – 6 – 5 – 2 – 7 – 1 – 4

The resulting word tells you
Where the Quest Box hides!
Search low under a circle
Near its outsides.

Explore the box’s contents.
Put it back when you’re done.
Then explore the marsh and mud
And continue to have fun.
