The mechanical structure and chemical composition of the rock, the local climate and temperature range, and the amount of vegetation and rainfall a region has all determine how fast a carbonate landscape erodes.
Karst along a seaside is quite different than that inland, and tropical karst does not resemble karst in temperate or sub-Arctic zones. Landforms in zones with earthquake activity are quite different than that in quiet zones, or places where mountain-building have turned the layers of carbonate rock on edge.
Some karst is formed as a result of sulfuric acid welling up from below instead of carbonic acid percolating down from above. Some places in the American West are a mix of the two processes. But the karst of the Missouri Ozarks is almost textbook, and is characterized by well eroded rolling hills, deep hollows, springs, caves, sinkholes, losing streams, natural bridges, and tunnels.
A few definitions:. A spring is a natural resurgence of groundwater, usually along a hillside or from a valley floor. She also was able to articulately answer any questions we had along the way, and even snapped our pictures on request at a few of the more scenic places.
Which there were a lot of! This cave is simply stunning to walk through, and to realize that the incredible rock formations are the work of the amazing power of nature. Highlights include the "big room," a chamber at least a football field across, the "twins," two giant stalagmites that have to be 20 feet tall, the unreal-looking flowstone or the lilypad room - the list simply goes on and on.
As does the tour, which took about an hour to traverse the main caverns. All that walking, by the way, is done on concrete paths with guardrails, so there are no worries about slipping or falling, as long as you're careful. And of course, no cave would be complete without bats. There are four or five species that inhabit Onondaga cave, and we were able to find examples of most of them, which our guide pointed out for us. I realize that most travelers probably can't get the great one-on-one tour experience that we did on touring Onondaga.
But even with a larger group, there's simply so much to see, and it's all so impressive, that I wouldn't hesitate to make this a part of your trip. It was definitely worth the side trip from Hermann, and even ended up being the highlight of the whole Hermann trip! Just awesome.

It is seriously mind blowing! Besides being a wonder of nature, the staff makes it even better, we had an engaged knowledgeable guide, Keegan not sure about the spelling that exposed every single detail throughout the tour.
We got a couple at the gift shop and they were pricey, so make sure you bring your own. I also must mention that the paths and handrails make it pretty easy to get around if you have no mobility issues. A1derbean Saint Louis, MO contributions. We found out about this place from a cavern map at our hotel in Sullivan.
We bought the combination ticket for both Cathedral and the main Onondaga cave. We did the am Cathedral tour, and only one other couple showed in addition to our guide. The tour requires a slow, unassisted third of a mile hike through the woods on a natural path in addition to the actual cave walk on some very slick, dark, steep paths lit only by the Maglites they loan for the walk. The hubs and I are middle-aged couch potatoes and it was hard, but we did it. It was the highlight of our 3-cave weekend.
Large tour groups, some pretty lovely natural features. It was really well done; family friendly with a lovely campground, really friendly, patient guides. The day was so pleasant and we got a chance to push ourselves in a safe environment. Mayga1 contributions. Scheduled tour times change depending on the season and available staffing.

Gigging for hogsuckers is a popular activity on fall evenings. Fishing licenses and bait are not available at the park. Blue Heron Trail: This trail connects the visitor center to the campground and is one-half mile long. It runs alongside an oxbow lake that formed when the Meramec River cut a new channel and began flowing along a different course. During the spring and summer months this trail is decorated with bright orange butterfly weed, wild hyacinth and delicate wild columbine, all of which grow along the bluffs and rocky hillside glades of this trail.
Blue Heron Trail is marked with blue arrows. Deer Run Trail: This trail makes a two-and three-quarter mile loop. It starts at the amphitheater trailhead in the campground. This cave, designated a National Natural Landmark, offers visitors views of high quality stalactites, stalagmite columns, rhinestone dams, cave coral, soda straws, flowstone, and draperies, which extensively decorate the cave.
