A mountain pine beetle infestation developed in lodgepole pine stands in the Gold Creek drainage in 1974. From 1974 to 1976 approximately 19,000 trees with an estimated volume of 10,210 cu m were killed. Based on buildup ratios, stand structure, size of trees, and residual green stand, it is predicted that 5,756 trees will be killed in 1977. Three management alternatives are discussed and selective logging is recommended.
