Graham Cave Trails natural surface section leads to Graham Cave, passing by an interpretive shelter with wayside exhibits and an overlook at a wet-weather waterfall. As hikers follow the natural surface trail to Graham Cave, they will be hiking along the edge of the Graham Cave Glades Natural Area. As part of the Missouri Natural Area System, this area still possesses much of the same character experienced by American Indians when they inhabited the region. Ascending from the valley, there will be views of sandstone ledges, often covered with lichens, mosses and ferns. Above the ledges are open, rocky glades. Plants such as prickly pear cactus, rushfoil, pinweed, rose verbena, fame flower, Missouri brown-eyed Susan, hairy lip fern and adders tongue fern are well adapted to life in the extremely hot and dry glade environment.
A really unique geological site to behold. Very quick and easy trip. Here's the info from the park-
"Graham Cave is unusual because it formed at a soft sandstone/hard dolomite contact. Because the St. Peter Sandstone has spaces to hold water, it acted first as a sponge. Water softened the cement holding the sandstone together and the rock was gently washed away over time, leaving an arched ceiling. The Jefferson City Dolomite floor dissolved also, though not as much as the sandstone. In most such contact caves, the dolomite is removed first, leaving a flat sandstone ceiling subject to breakdown. Graham is an excellent example of a rather unusual method of cave formation."
Nice geological feature. Other nice short hikes at the park and nice campground facilities. It is a good camping area when traveling along I-70.
