Increasing each day as time passes

Vegetation abounding

Blending with its surroundings

You may need to put on your glasses

In the last set of clues, as you know

The reference point two four oh oh 

A post denotation

East of the location

Two hundred paces or so

Not far away is a tree

Though this tip may be a key

Do not look up high

On the ground it will lie

You’ll need to be bending your knees

On the playground south of the pool 

In the grasses clumped in a slough

With the stop sign

Your sights should align

Search way down deep where it’s cool

If at first you believe it’s not there

Keep digging and take extra care

The medallion indeed

Hides down in the reeds

It may have been shoved down a layer
