From Recreation.gov  -“Iron Creek Campground sits near the confluence of Iron Creek and the Cispus River. This large campground winds through a forest of old-growth Douglas firs, cedars and hemlock. Lush vegetation and ample space between sites offers excellent privacy.  Located in southwest Washington State, the Gifford Pinchot National Forest encompasses 1.3 million acres and includes the 110,000-acre Mount St. Helens National Volcanic Monument established by Congress in 1982. Iron Creek is part of the Cowlitz Valley Ranger District, which is located in the northernmost portion of the Gifford Pinchot National Forest. This District is roughly located among three volcanic peaks: Mt. Rainier to the north, Mt. Adams to the east, and Mount St. Helens to the west.”
