Nob Hill Nature Park, St. Helens

Nob Hill Nature Park is a 6-acre oak woodland located in St. Helens, Oregon, 30 miles north of Portland, Oregon. Perched on a basalt bluff, it overlooks the Columbia River, at the point where Multnomah Channel joins the Columbia. Along with white oak trees, or Quercus garryana, it also has a wide array of native wildflowers in spring, including camas, trillium, iris and larkspur. It also has plenty of invasive plants, including blackberry, English ivy, lunaria, vinca, mullein, thistle and tansy. There is a lot of poison oak too, which is commonly found in western oak woodlands. Long pants, long sleeves and heavy shoes are recommended to prevent any skin irritation. ()
