It's a modest metal plaque, affixed to a boulder at the Afton State Park Visitors Center, inscribed with just a few words: "Dedicated in honor of Chester S. Wilson/St. Croix Valley resident/Commissioner of conservation 1943-55."
Unpretentious as the marker is, its setting is fitting: Wilson was instrumental in helping secure the prime real estate along the St. Croix River that gave Washington County its second state park.
Beyond that, the longtime Stillwater resident's far-reaching imprint on protecting the state's air, water and environment can still be seen from the Boundary Waters Canoe Area Wilderness to state park entry stickers and even to the creation of the state Department of Natural Resources (DNR) itself.
A few years after coming home from military service in World War I, Wilson was elected county attorney. His skill and personality, though, put him on a track to public service. He worked as an assistant attorney general, with a brief break, from the mid-1920s through 1943.
It was during this tenure, in 1931, that he drafted the legislation that for the first time merged all the state's environmental agencies into one, the Department of Conservation, which eventually was renamed the DNR in 1971.
The unification of four units of state government responsible for Minnesota's dwindling natural resources — forestry, game and fish, drainage and waters, and lands and timber — culminated years of struggle, according to the DNR. The new agency traced its roots to commissions and departments set up in the late 1800s to manage state resources.
The work of those early agencies was, at best, uneven, and at worst, ineffective and fraudulent. "Previous to 1931," said an early department report, "conservation progress in Minnesota was both painfully slow and haphazard."
Wilson had no inkling what would happen a dozen years later. With World War II raging, Gov. Harold Stassen asked him to take over the agency Wilson had helped to create.
