North Dakota

Medicine Hole, this is a cave. But the article does explain why there are not many other caves in North Dakota. Find photos and notes on Ice Caves and Snow Caves. Also provided is info and pictures of Bear Cave, Lions Cave, Hideout Cave, Bismarck Cave, Washburn Cave, Keller Cave, Bear Den Cave, Erosional Pipes. These are indeed wild caves and there are no tourist attractions. There is also a fine piece about underground mining. A really great website.

Theodore Roosevelt National Park, the Wikipedia page Find lots of history and description but also some beautiful photos. The National Park Service includes the above and several other parks and places.

North Dakota, the Official Portal for North Dakota State Government and be sure to read the About ND to find how small the cities really are. See what is produced in the state and learn all about the state. This page is infoplease but be warned that it comes with a popup that my firewall could not keep out though it said that it did. The site does have some interesting info. It is mentioned that there are 17 state parks but says nothing about their names or where in the state they are located. This site is about. com which I dislike but they do tell of 3 of North Dakota's state parks. The official state parks website.

Lakes and Rivers, by VistaUSA. And here I was about to decide that ND didn't have any rivers or lakes. Beautiful.

Knife River Indian Villages National Historic Site There is a tiny bit of history and one photo. There is a list of surrounding communities.

Fort Union Trading Post National Historic Site another brief history with one photo. A very pretty photo at that. There is also a list of surrounding communities.

Homme Lake, Dakota Prairie Grasslands, Badhill Dam Lake Ashtabula, Devils Lake Wetland Management District, Kellys Slough National Wildlife Refuge, Arrowwood National Wildlife Refuge, Chase Lake Prairie Project WMD, Kulm WMD, Lake Alice National Wildlife Refuge, Sullys Hill National Game Preserve National Wildlife Refuge, Audubon National Wildlife Refuge. These all fall in the state parks and preserves. There was no other information available about any of them only a list.

North Dakota Rivers, The USGS has a fine page aimed at canoeing that has some great info and photos about the following rivers: Knife River, Little Missouri River, Pembina River, Red River, Sheyenne River, Souris River, Yellowstone River. Also see the Wikipedia page has a listing of Rivers of North Dakota.

Bridges, The Wikipedia Page and The Liberty Memorial Bridge (this is a work in progress- read the history of how this beautiful bridge came to be, the purpose served and the building of a new bridge. The photos are supreme and be sure you take the time to read the history the the project time lines and tables.) Did you know that North Dakota has more than 5,000 bridges? The G.H. Railroad Bridge, 6 miles West of Minot, N. Dakota. 
More Bridges of great interest: The Fairview Lift Bridge, The Snowden Lift Bridge and the Cartwright Tunnel are a set. CLICK HERE and read the most interesting history and description of the times and trials of the past. There is even a photograph. And The "Stephens Bridge" in Stanton, North Dakota. This is a waymarking page with one photo and almost no history.
I was looking through the webpage for castles when I found only one for North Dakota. There was little info but directed the reader to their website. It is part of "Preservation North Dakota, Preserving Prairie Places" and the castle was listed as part of the 3 most Endangered. They are Coglan Castle, Hutmacher Farmstead and Plaza Community Museum. Much information and excellent history. Lots to read and enjoy.
Landforms, The Great Plains of North America slice across North Dakota covering about 50% of the state. In the far southwest, the Badlands, a long series of unusually shaped and brightly colored buttes, domes and rolling hills dominate the landscape. White Butte, the State's highest point, is found here. Read more about the area's rivers, streams and lakes. Nice map to see where those rivers and lakes are located.
Sheyenne State Forest Water Falls "The Sheyenne State Forest found in Ransom County has the only natural waterfall in North Dakota..."
