*726 A 72-foot diseased tree fell on a sleeping child's tent pitched in a campground that is located within a vast public wilderness park. The park's owner, the County of San Mateo, contends it is immune as a matter *140 of law for this allegedly dangerous condition of its property under Government Code section 831.2, commonly referred to as the "natural condition immunity." It states: "Neither a public entity nor a public employee is liable for an injury caused by a natural condition of any unimproved public property, including but not limited to any natural condition of any lake, stream, bay, river or beach." 1 (See § 831.2.)

The trial court denied the County's motion for summary judgment under section 831.2, and we now deny the County's petition for a writ of mandate seeking to overturn the summary judgment ruling. We conclude there are triable issues of fact as to whether the property here was "unimproved."
