“In knee-deep snow I went to look—and was amazed,” - Dr. Max Partch recounting his first visit to this area in a 1966 Conservation Volunteer magazine article.This ‘big woods’ forest is a sight to see. The understory of wildflowers and ferns can give you a sense of wonder, just as Partch did when he first walked through. Though you may not visit this SNA in person, it is rewarding to know that we, as Minnesotans, have together protected this important habitat for the rare and wild in Minnesota.
