The New England Botanical Society is leading a walk on September 6 to Rattlesnake Mountain in Rumney, New Hampshire. The leader is Scott Bailey, retired US Forest Service ecologist. Rattlesnake Mountain is part of the White Mountain National Forest. There are cliffs of multiple lithologies, talus, and rich northern woodlands. The site is likely the northernmost station for white oak in the Merrimack watershed and contains good diversity of ferns, including Dryopteris fragrans. The trip will cover a moderate distance. Some areas may be challenging with steep and rocky sections. Register HERE. Free.
