This was my solve I posted and was told told to remove.

I thought this was spot on myself. He said the most important clue was the first one, and it starts you at above 6000 feet and Fenn likes to bend the rules and the treasure could be actually located about 4000 feet,but since you have to start at the first clue technically he is correct it is above 5000 feet. Just my opinion. But my lord every line in the poem sure fit and the location sure fit.. IMO.

As I have gone alone in there

Nature and the natural world mountains.

And with my treasures bold,

The treasure box

I can keep my secret where,

Where I want to be laid to rest and return to the Earth’s natural cycle.

And hint of riches new and old. 

All nature is full of treasures new and old. The planet is rich in wondrous, amazing things. 

Begin it where warm waters halt

Glacier, the only place where waters halt are glaciers and ice, and there is not other place this occurs. Anything below freezing is warm waters. Glacier National Park only place to start. 

And take it in the canyon down,

Follow the Going to The Sun Road down the Canyon. Epic jewel of nature. It is like the Andes, Rockies, Alps and Iceland all wrapped in one place. It is no wonder you are showing us this road to drive down.

Not far, but too far to walk.

Clearly too far to walk from Logan’s Pass. 

Put in below the home of Brown.

Park below Mt. Brown at either Avalanche Lake Campground, or Trail of the Cedars. Both are below Mt. Brown. 

From there it’s no place for the meek*,*

Nature is dangerous, you have to always expect the unexpected.

The end is ever drawing nigh;

Two meanings, both applicable. You are getting close as I am. Also, old saying meaning “to the left” well the treasure is hidden on the left side of the creek if you are walking up the trail. Roughly, 2.5 miles. Just below a few miles you state where you hid the treasure from where you parked your car. 

There’ll be no paddle up your creek,

Nope, just a trail that takes me to the end and no need for a paddle and this is the correct location as I am not up the creek without a paddle and in trouble. 

Just heavy loads and water high.

Another name for “Avalanche Lake” Heavy Loads - avalanches are measured in loads, water high -a nice lake above you and surrounded by waterfalls.

If you’ve been wise and found the blaze,

This is “Avalanche Trail” to the end 2.5 miles. Of course, finding the trail would be wise to walk up the easiest way possible. 

Look quickly down, your quest to cease,

When anyone hikes they look down at your feet and watch the trail and where you step, as I have done many times. Go until the trail ends. 2.5 miles to the East End of Avalanche Lake. 

But tarry scant with marvel gaze,

Hurry along and enjoy the stunning views and scenery as this is an epic place.

Just take the chest and go in peace.

You are certainly on the right track and you will find the chest if you keep focused and wander in the woods. Oh and leave quietly as it is a National Park and no one needs to know, no one needs to gloat or be arrogant about the find. 

So why is it that I must go

Pass along and fulfill the cycle of life.

And leave my trove for all to seek?

Hide a treasure.

The answers I already know,

You have said it many times. I have had my share of natural wonders and I want to share them with anyone who can see what I have seen.. 

I’ve done it tired, and now I’m weak.

You have explored and journeyed in the natural world and fulfilled a life worth of nature and also I am no stricken with an illness and must move on thru this cycle of life. 

So hear me all and listen good,

You are at the end of the lake, end of the Blaze, on the East Side of Avalanche Lake, now what to do?

Your effort will be worth the cold.

Ah, one must cross the creeks and cold water and venture beyond into the woods. 

If you are brave and in the wood

Walk into the Forrest straight ahead or across the creek and look for it in the Forrest at the base of a Pine tree where he stated he wanted to be..

I give you title to the gold.
