The reservation of Fort Snelling contains 1,531 acres, though originally this tract was much larger than now. The fort structure which one sees from the river is an irregularly shaped bastioned wall conforming in outline to the high plateau of land upon which it is situated. It occupies the extreme end of the point of land formed by the juncture of the two rivers, and on the Mississippi side the bluff upon which the fort is situated descends abruptly to the water, the river there running almost in a canyon. On the Minnesota side the slope is more gradual and ends in a low marshy flat which extends from one-third to one-half a mile and is frequently submerged during high water. The altitude of the post plateau above the river is 300 feet. The establishment of Fort Snelling was one of the fruits of the work of Lieutenant Z. M. Pike, the first American to explore and chart the peak which bears his name. In 1805 this officer was in command of an exploring expedition and held a conference with the Sioux Indians on an island at the mouth of the Minnesota River which now bears his name. He secured from the Indians for military purposes a strip of land nine miles on each side of the Mississippi River and extending from the conference island to the Falls of St. Anthony, near which Fort Snelling is. It is to be remembered that in 1805 the settlement of the American nation did not extend beyond the Mississippi River. The country west of Lake Michigan and on the headwaters of the Mississippi River, though a part of the United States, thanks largely to George Rogers Clark, was in a state of nature with only the trails of Indians and traders and the remains of little French settlements as the foundation for the civilization which was to grow up within it. The privileges which Lieutenant Pike secured from the red men were not immediately taken advantage of by the United States authorities. Time passed and the War of 1812 with England gave the War Department of this country quite as much as it could take care of. Finally, in 1819, Lieutenant Colonel Henry Leavenworth, of the Fifth United States Infantry, was sent with his regiment to locate a fort upon the reserve selected by Lieutenant Pike. Colonel Leavenworth reached the headwaters of the Mississippi without incident and rendered his first monthly report in September, 1819. Scurvy broke out now among the troops and this, added to the natural inclemencies of the climate here in winter, prevented any work being done until the spring of 1820. In May, 1820, Colonel Leavenworth moved his troops to a point on the west bank of the Mississippi River, about a mile and a half above the present location of Fort Snelling. The site chosen by him for the fort was the present military cemetery. He made preparations to commence the work, but Colonel Josiah Snelling assumed command in August and selected the location where the fort now stands.
