They’re going to be looking to “round up” the noxious plants in the Mount St. Helens National Volcanic Monument at tomorrow’s 7th annual Weed Rodeo, and you can help out. The Forest Service says that the goal is to help remove scotch broom and other noxious plants near Coldwater Lake. Registration starts at 10 am at the Coldwater Lake Boat Launch, and the effort will continue until 4 pm. Make sure to bring gloves, boots, long pants, lunch and water. Hard hats and safety glasses will be provided. Those who pre-register will be allowed to camp overnight at the Science and Learning Center at Coldwater, and on Sunday morning, volunteers will be treated to a hike guided by Monument Scientist Peter Frenzen.
