Mastodon State Historic Site

Park Information

Looking to take a trip to where something big happened? Try Mastodon State Historic Site. The site is the home of the Kimmswick Bone Bed, one of the most famous and extensive Pleistocene ice age deposits of fossils, including a number of bones of giant mastodons. Interpretative trails and picnic sites dot the landscape and a museum tells the natural and cultural story of the Clovis culture, which existed in the area between 10,000 and 14,000 years ago.

Sometime between 1936 and 1938, the Missouri State Society Daughters of the American Revolution published “The Old Tavern; Book of Recipes,” which contained more than 700 recipes from DAR members and the J. Huston Tavern at Arrow Rock State Historic Site. The recipes offered a unique glimpse into our food culture during the early years of the 20th century. On page 36 is a recipe for buttermilk biscuits: “Add to ½ sifter of flour, 1 scant tsp. soda, ¼ tsp salt, 2 level tsp. baking powder. Sift into mixing bowl. Cut in with fork 2 heaping tbsp. lard, 1pt. buttermilk. Turn onto floured board, knead to soft dough, Roll 3/8 inch thick. Bake in greased pan in hot oven. 30 biscuits.” You can try the recipe itself or enjoy the fine food served today at the J. Huston Tavern, the oldest continually operating restaurant west of the Mississippi. For more information, visit http://www.mostateparks.com/park/arrow-rock-state-historic-site.
