If you're like me you probably didn't know ACEC meant Area of Critical Environmental Concern when you saw this spot on the map. ACECs are designated by the Bureau of Land Management in order to preserve and protect areas with unique flora & fauna. King Mountain was designated as an ACEC due to two rare plants growing in the area, but bring your camera even if you aren't a botanist as the views from the summit are great.
