Poem Solution

This is a solution to Forrest Fenn's poem that ends at the treasure location.

This is largely a guess that uses a straightforward poem interpretation.

You can read Forrest Fenn's poem here.

Nearly all rivers begin in distant headwaters, but not The Madison River. It begins mid-course as an already large river. The warm water of the Firehole halts as it mixes with the cool water of the Gibbon and forms the Madison.

Drive down Madison Canyon - it's too far to walk.

Stop at the famous home of large Brown Trout: Nine Mile Hole.

Put into the water just below the rock pictured in The Thrill of the Chase.

No boats / no paddling allowed - crossing the river is not for the meek.

Known for holding brown trout of record-breaking weight (heavy loads), 

the deep pools shelter the fish, the water high above them.

Now, look for the blaze.

Perhaps a marking carved on a tree. From Jack's account, the blaze was damaged. Perhaps the particular tree happened to fall, or another tree fell on top, or otherwise.

Having found the blaze, look down, sweep the dirt off the chest, and celebrate the find.
