Geo 365: Oct. 5, Day 278: Echoes

One of the things I find especially appealing about this area is the way the inorganic pillars and the trees echo each other. The Pinnacles are described as the remains of fumaroles, where hot gasses escaping from the tuff altered the surrounding rock, cementing it better and making it more resistant to erosion than in areas farther away from such vents.
