Temporary Closure
In November 2017, small flakes of paint containing low levels of lead were discovered near the Mount Umunhum radar tower. Out of an abundance of caution for the safety of the public, the area surrounding the base of the radar tower and pathways leading to the area are temporarily closed to public access.
