Hume Lake, in the northern portion of the monument, is a beloved, year-round recreation destination where visitors can enjoy fishing, non-motorized boating, hiking, mountain biking, and camping during the summer months. In the winter, snow play is wildly popular among visitors. The shoreline of the lake is followed by an interpretive trail.
For the history and architecture buffs in the audience: this 87-acre lake, which was originally a mill pond for an historic logging operation, is formed by a unique, historic concrete multiple arch dam. This dam was constructed in 1908.
