Camp Siman is a former Tiff Mine started in the 1890’s and closed in the 1970’s. 152 acres of hardwood forest with bands of cedar forest, a 10 acre lake, a dam 1800 Ft. long, 60 Ft. high on the wet side and 103 Ft. high on the dry side and 60 Ft. wide on top, the spill way is 1000 Ft. long, 60 Ft. deep and 60 Ft. wide. The road network is made of crushed rock up to three Ft. thick and 10 or more Ft. wide. The terrain is varied from typical MO Ozark woods to moon scapes with large piles of rock of various sizes, test digs, canals, ravines and open areas.

Work started on Camp Siman in November 2014 with the first several months spent on clearing the sides of the 1800 Ft. long dam. Since then the work has concentrated on clearing the preexisting roads and opening up the Reception Center and the Cantonment area. At this time we are set up to host almost any type of event. Once we have a couple of events to raise some funds the road improvements will be complete and we will be able to traverse the entire property with any type of vehicle, Military and POV.

Camp Siman is primitive, NO utilities of any kind, we do have one pit toilet finished with three more planed in the near future. We have 152 acres of land divided into five Ranges each @ 30 acres or so. The Reception Center is designed to accommodate any Vendors, S&A, Registration and Field kitchen as well as a large common fire pit area.  We use military style fly’s and all types of tents when appropriate. As the Reception Center is multipurpose you will find nonmilitary items as this area is administrative and not meant to be period correct.

The Containment area is divided into four sites, US, British/Commonwealth, Axis powers and the Soviet Union. Each camp site has a burn barrel and a fire ring all supplied with firewood. The US camp can accommodate up to two GP medium tents with room for many more types at the same time. Camping is available for most events if requested in advance or if planned as part of the event.

We have several secure parking areas whiten the site. Large attendance will necessitate the use of the dam which will accommodate up to 80 cars, a small parking lot is planed near the crossroads which will hold up to 20 vehicles and the area known as Seven Pines will hold 40 cars.

Camp Siman will for now only host WW II Events with the hope of adding WWI, Viet Nam and Air soft in the future. If other time periods are interested we will consider. All Events are fundraisers for the improvements at Camp Siman.

Camp Siman Events and First Special Service Force 6th CO 3rd REG  has one philosophy; we are here to have a good time. All participation impressions are to be historically correct and we follow all HRS and FSSF 6-3 Rules and Regulations as well all Local, State and Federal laws were applicable.

Please support and attend our events and help make Camp Siman Events, Tiff, MO one of the destination sites for our hobby.

Thank you,
