Hiking Update: Mt. Jefferson Expedition Sellers & Morgan hit the hills again and ascended Mt. Jefferson in the Presidentials. New England's 3rd highest mountain (5716') was made by way of the challenging but striking Castle Trail. This path runs up and over the narrow and craggy Castellated Ridge to the rocky summit cone of Jefferson. (Great hiking surface!) A long and tiring day but well worth it. This was Vicki's #11 4000' footer in NH. A trip report can be found here.
