An obsolete United States Geological Survey (USGS) stream gauging tower, a frequent target of graffiti taggers and forest explorers in Eaton Canyon, is now sealed.
According to MyEatonCanyon.com, the station was once part of a network of facilities throughout the country used to monitor water levels in natural waterways.
Large steel sheets were installed by the USGS in late September to block entrances to the tower, which is slowly returning to nature.
Other disused water-related bunkers installed in the upper canyon within the jurisdiction of the U.S. Forest Service remain accessible to hikers.
