2021 Coldest's Lost Treasure Hunt - Critical Clue

End this mission, and improve your position,
To do that you’ll need a big leap of faith.
A UFO shape, will help crack the case.
It crashed just off a trail — from outer space.

As it takes flight, don’t look into the light!
Not all UFO’s have a rounded shape.
To crack this nut, you should trust your gut. 
In a park next to a gathering place.

In the city of Hills, travel where god wills.
In the Prism the Dark Horse sits and weeps.
Find 3 in a row, the frog knows where to go!
Down the wooded trail you’ll take your leap.

Grab your Nutella, leave your umbrella,
Some tree cover will make you a winner.
With clues to harden — apply to Arden.
Down a foot trail, just over some timber.

Go on a lark, in Hazelnut park!
Here resides the alien prize to clench.
Start at the lot, head north on your trot,
Through the woods just past the final bench.

Look to your right, a lone foot trail in sight,
Take it to some timber — but do not trip.
Make your big leap, for the prize you’ll reap,
Just over the tree you’ll find the spaceship.
