The Allison Wonderland

Great noodle!!! That’s what I was trying to figure out with the art! Where the clues lined up and where to dig

Good one! With St.Anthony!RR on mapguys book refers to a sign that states “Three Rivers Park District Boundary Ordinance Enforced”.  Maybe this was the rhyme reference?“Spring from the mud” could mean a muddy trail or unpavedThe #2 poem closer to lake shore and closer to Silver Lake Road by the picnic table and fishing pier references: deep into the night                   transported to tranquility                    guided by wisdom’s gentle voices                   warn against illusions-test heart’s truth                   mysteries veil of past and future                   Ancestors of the North       *these are lines from the poem that you can listen to when you take the tour. 
I think the island is wrong to be looking on

"goals" is another hockey reference.  "Strap on your mask" in Clue 1

I'm starting to think that many of the clues with a numerical equivalent are referring to stops on the Sculpture Tour.  A week =7 days --> Stop 7.  "Circle of stones" also maps to Stop 7.
Two weeks = 14 days --> Stop 14.  That piece is titled Still = "stay"?
Delta is the 4th letter of the Greek alphabet --> Stop 4 = flood. 
Omicron is the 15th letter of the Greek alphabet --> Stop 15 = heart of hearts? Located in upper middle of perimeter formed by the other tour stops. 
I think I'm onto something here with the tour stop numbers... just can't quite decide where best to dig. 

"all of us spring from the mud" = Sculpture titled Archenteron - the description of the piece is: 

The title Archenteron, refers to an early developmental state that all living creatures take before developing into their own distinctive biological directions.

My wife the good catholic reminded me that St. Anthony is the patron saint of lost things- which is quite fitting for the hunt.

Agreed. It appears that we can interpret the clues more literally than in most years.

An anagram for marathon is Roman hat.  IDK if it means anything, but seems a curious tie to legions in Clue 8?  
Another is MN oat rah = CHEERios!? LOL.  Still another is at no harm = Search, don't destroy

I definitely made the mistake again of thinking the cluewriter had come up with clever riddles to solve. But no, they were just throwing out the names of things they saw in the park.

One of the sculptures on display is entitled Eterne = Life Eternal.
Another sculpture, Thoughts From the Earth, is literally a circle of stones.  LOL. Can't believe I didn't realize this sooner!

Thanks for posting this. I fell asleep before the clue came out. But I would say this is definitely the Salvation Army clue referring to Silverwood.

Salvation Army really fits.
A Legion is said to be many, a roman army of 6000. Some say 3000-6000. The Swine were 2000 in number for the unclean legion of spirits that entered the swine.For he said unto him, Come out of the man, thou unclean spirit. 9And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many. 10And he besought him much that he would not send them away out of the country. 11Now there was there nigh unto the mountains a great herd of swine feeding. 12And all the devils besought him, saying, Send us into the swine, that we may enter into them. 13And forthwith Jesus gave them leave. And the unclean spirits went out, and entered into the swine: and the herd ran violently down a steep place into the sea, (they were about two thousand;) and were choked in the sea.

Starting to feel like the ol red herring hunt maybe just started to reveal itself.
Stuff here still works for silverwood - but it’s moving a bit away IMO.
Legions refers to an army it seems maybe the Salvation Army…but
“Legions/Regions” rather than “legion/region” is entirely unnecessary unless they were pointing to two “regional” parks occupying closely - eg vadnais snail or say HF/Crosby
Two weeks is a “Fort”nite after all.
If it is down there- we will go the distance I imagine- lots of ground, lots of snow.

Clue #8If saving souls is among your goals
Then this hunt is for you
Bring your legions to these regions
And stay a week or two
Clue #7 Scale the heights, look for the brights Where nature inspires the arts Is it life eternal or heat infernal That strikes at your heart of hearts?   Clue #6 Ride this rhyme for a trip through time From stone circles to the flood From a raised elevation you'll make observation That all of us spring from the mud   Clue #5 When the buttons showed up, we screamed out ‘what?!?’ Still, we didn’t cancel the order So when we hid the puck, we pushed our luck And hid it so close to a border.   Clue #4 An item hot is the current lot Of at-home tests for COVID Ours is nice, in block of ice Inside the medallion's hid   Clue #3 Far from the path that leads to a bath The treasure waits so alone Step out of the dark and go to the park But avoid obstacles of cone   Clue #2 Get out of your bed if you want some hunt cred Don’t wait ‘til temps hit the 30s With the prize as your driver be a vigorous striver For success means a life of ease   Clue #1 From delta to omicron, what a marathon Getting from last year to this Strap on your mask, get down to the task Let fresh treasure be your bliss

I was thinking that was in reference to dyers garden

Life eternal = churchesFire infernal = the stone fireplaceHearth of hearts = weddings they do there

Salem may fit the "life internal heat infernal" clue.  Salem witch trials - those found guilty were burned at the stake.  Innocents killed would presumably go to heaven.

There is a church called Salem a block away on silver lake road, heaven and hell?

There are churches in the area, though there are churches most everywhere. Maybe it's a reference to "salvation"? As in the Salvation Army used to own that site I think. It could be something in the park too as I have yet to ever go there.

Heart of hearts is a phrase used in Shakespeare's Hamlet.  Hamlet is a tiny settlement smaller than a village.  St Anthony village perhaps?

The third line has me stumped - clearly refers to the choice between heaven & hell.  Thoughts?
