D&D Re-Tee Beers for Tears Hunt

"known all over," "home of Brown," "traffic the booze," "purgation by conflagration," "settle," and "Sintomonee" (SINce + TO + MOsey + NEEd) are all meant to suggest Hidden Falls Regional Park. Source: The Street Where You Live by Donald Empson.
"traffic the booze" is also a reference to this hunts "liquid prize" of six beers, hidden near the trophy.
"ken" is a shoutout to Ken "Diggorius Rex" Ng—our gracious host for the D&D Halloween Hunt—and a reference to Kenneth Street, situated to the east of the trophy's hiding place.
"forest fen" is meant to suggest searching a frequently flooded, marshy area in the Hidden Falls woods.
"Before" is meant to suggest Prior Avenue, which runs into Hidden Falls Park at is (closed) southern gate.
"fall" could be taken to suggest Hidden Falls.
"the spot has been repurposed" is meant to suggest that the area was turned into parkland after its "purgation by conflagration."
"parking lot resurfaced" is meant to suggest the Hidden Falls' oft-flooded parking lots; the flooding mandates frequent repaving.
"Just follow the prints!" is in reference to the 2007 Pioneer Press Treasure Hunt; Rob and Jake won that year in three clues by following the Cluewriter's footprints to the hiding spot. The trophy was hidden just north of that area, in the southern part of the park.
So, basically: Look in a well known Saint Paul park historically known for Joseph R. Brown's "Sintomonee" settlement—where liquor was illegally trafficked and settlers' structures were razed—at the base of a tree in a marshy area of the woods, away from the creek and south of a (frequently flooded) parking lot, near where Jake found the 2007 PiPress puck.

Hoping that folks got the brown/ Sintomonee reference to Hidden Falls park in clue #1, this clue aims to give direction within the park by giving a starting landmark, a direction of travel and features near the hiding spot (power towers & Red Oak tree). Full explanations below.
