There are signs of human settlement in the area from as early as in the late 19th century. The area's forests have been utilised for hundreds of years and the River Korojoki and its tributaries have been log floating routes. Signs of log floating are visible at the River Kurttajoki in the Koivuköngäs area. Other signs are the remains of an old loggers´ lean-to shelter by the trail leading down from Saukkovaara Hill and the remnants of an old log floating flume halfway down the River Korojoki.
The area's farmers have taken their cattle and sheep to graze in the natural meadows at the bottom of the valley. The grass in these meadows was also sometimes mowed, stored in barns and used as feed for livestock. Bears and eagles tended to prey on sheep. The foundations of old barns can still be found on the river bank. Some of the natural meadows and barns are to be restored so that future generations will be able to see them as well.
