FY 1947-48: A towersite on the Deer Run State Forest was acquired. (Missouri Conservation Commission Annual Report)
March 17, 1949: "Two Conservation agents are investigating the origin of a forest fire which blackened a thousand acres of the upper Current River country north of here last week, said Lee Fine, district forester for this area. Fine said his Hartshorn towerman sighted a small blaze at 9 P.M., Monday. Before crews organized an attack, the fire was apparently 'strung' for more than two miles by horse mounted arsonists. Suppression was greatly impeded by high winds plus the persistence of the 'fire bugs', who continued to string flames throughout the night. Forestry crews were assisted by Pioneer Cooperage employees but despite their combined efforts the fire raged nearly 24 hours before being brought under control." (The Index)
