In 1974, the National Park Service closed the visitor center and accommodations at Manzanita Lake, fearing that these buildings would be in the way of a rockslide from Chaos Crags if an earthquake or volcanic eruption occurred in the area. In 2011, twenty wooden cabins, along with picnic tables, fire rings, and food lockers, were reinstalled in the Manzanita Lake Campground. It had been determined in the 1980s that the rockslide danger had been overstated by the USGS (after the cabins were torn down), and therefore, the cabins were reintroduced to the park for nightly rental.
