Above, the view from the Missouri River of the Fort.
Modern day entrance next to the Education Center. Fort Osage is roughly 20 miles east of KC off 24-hiway. Directions are on their website: http://www.fortosagenhs.com/
Lobby area and gift store.... you buy tickets here.
Above and below.... binoculars and a telescope aid visitors in looking for birds that inhabit the area.
Above.... the guards are all dressed as foxes.
The museum in the lower level gives an overall introduction to the plants and animals of the area as well as information about the Osage Indians and the operation of the Fort.
A patio/deck has additional information about wildlife. The Sibley Power Plant can be seen in the distance. 
Leaving the visitor center you proceed to the Fort.
A garden was maintained outside the walls as space was at a premium inside.
Outer gate.... there's an inner gate also... 
Inner gate with the officer's quarters visible in the opening.
Folks in period garb can answer just about any question you can think of. 
Soldiers quarters.... dirt floor and un-compfy bunks.
Another view of the officer's quarters.
Cannon ready for action.... sort of.... along with openings for rifle fire....
Not a bad view.
Although the practice was banned in 1812, soldiers who misbehaved could be lashed in the middle of the courtyard prior to that date.
Looking out the interior gate down to the Factory House where trade was conducted between the Fort and the Indians and between trappers and the Fort. Fort Osage served many purposes including providing protection for trade and being a haven for westward travelers.
Happy visitors... non-period attire.
A demonstration of how to load a firearm from the period. Military standards dictated that a round should be fired every twenty seconds.... not easily done.
Yes.... they had double hung windows in 1808. In fact the Fort has been reconstructed according to the original plans that are still kept in Washington, D.C.
Lowest portion of the Factory House has a red line on the wall. Below the line the wall is original... above reconstructed.
One of the kitchens.
A fire is kept burning outside.... and normally in November would be a welcome place to sit.... but this was last Saturday and it was 75.
There is a boat landing below the Fort.... so, conceivably one could put their modern day boat in the water at Kansas City's (original) Riverfront Park and sail to the Fort for a little day trip.There is much more to see than what I've shown here.... great trip for kids (we big ones too).
