One bird, within a connected shoreline.

Reverse design anatomy
The Mint identifies a common loon with a rock cliff behind it. The engraved bird occupies the foreground while trees and shoreline recede toward the right.
The following close reading describes visible forms. It does not assign undocumented intentions to the artists.


A long bill and patterned neck identify the focal form. The species name is sourced; no call, nest or migration is implied.

Low ripples run below the patterned body. They are visible marks, not measurements of depth or water quality.

Upright trunks separate rock and open sky. Individual tree species are not assigned from the coin.
The place behind the coin
NPS describes a meeting of northern hardwood and southern boreal forest, with lakes and wetlands linked to the surrounding land. Fire, beavers, invasive species and active monitoring are part of its ecological account—not a claim of pristine, static wilderness.
The Mint calls 1971 the establishment year. NPS park history distinguishes the January 8, 1971 authorizing law from the April 8, 1975 order formally establishing the park. Both milestones are retained.
Historical context, not a reconstruction. No unverified event photograph is used.
Same design. A larger canvas.
The 2018 design also belongs to the circulating quarter. At 76.2 mm, the five-ounce silver coin is 3.14 times wider by diameter—not 3.14 times heavier.

The quarter is a measured outline: an exact authorized quarter photograph is not bound for this page. It is not a miniature bullion image.
