natural area

Located in the Hughes Mountain Natural Area is a trail called Devil’s Honeycomb Trail. It consists of glades, savanna, old fields and it is half forest. Polygonal columns of rhyolite make up what the locals call the Devil’s Honeycomb and is located at the highest point of the mountain. It is one of Missouri’s geologic wonders.

Around 1.5 billion years ago the rocks were liquefied by volcanoes associated with the St. Francois Mountains. The molten rock contracted, and as it cooled cracked and created multi-sided columns and created a rhyolite formation that locals named the Devil’s Honeycomb. The Precambrian rock outcrops are among the most ancient, exposed rocks in the United States.

The Hughes Mountain Natural Area is located off highway M, 3 miles southeast of Irondale.

Hughes Mountain is located in southern Washington County in Missouri. The area was designated a natural area in 1982. It is made up of a combination of igneous glades and three types of forests. Precambrian rock outcrops found in the area are 1.5 billion years old making them among the most ancient, exposed rocks in the United States.

The area is named after the first European settler, who arrived in 1810, John Hughes. The Conservation Department purchased the land from the Hughes family. The rhyolite formation located at its highest point is known by locals as the Devil’s Honeycomb. Because of my late start and other time restraints I was unable to make my way to this area. Another trip is planned for the near future.

Glades located within the area are natural openings located on the western and southern slopes where native grasses and a variety of wildflowers can be found. Glade plants include little bluestem, broomsedge, poverty grass, flame flower, prickly pear cactus, yellow star grass, spiderwort, and wild hyacinth.

The trail is 1.6 miles long and is an out-and-back trail near Irondale, MO. I found it to be a moderately challenging trail but was fairly well maintained with trail arrows. On average it takes 48 minutes to complete however time gets away from you when snapping photos. The trail is open year round and dogs are welcome but they must be on a leash. The trail is popular among birders, hikers and runners. However, if you see me running, run, because something is chasing me.
