Active fire suppression began after the Superior National Forest’s creation.

Evidence

To generalize from this record, it is helpful to group the data by cultural history periods (Table 3). Effective fire cont,rol began soon after the Superior National Forest was created. The last year that saw major burns in the virgin forests was 1910. I therefore call the period from 1911 to 1972 the “Suppression Period.” The period of active settlement, prospecting, and timber looking, spanned the years from 1868 to 1910, and I term it the “Settlement Period.” The fire scar and stand origin record begins to fade about 1727-note the erratic and widening intervals between fire years before then. — Miron L.
