Logging resumed in 1912 in the north part of the canyon, where The Boone's Ferry Wood and Tie Company had a site near what became Alfred Street. A sawmill and steam donkey engine operated near what became the sites of Beaver Bridge and Obie's Bridge. The lumber was used chiefly for railroad ties, cordwood and flagpoles, and left huge cedar stumps that remain in the park. Intermittent logging continued through 1961, and a 1962 windstorm known as the Columbus Day Storm blew down many remaining trees.
