The Sibley expedition visits the salt flats in northern Oklahoma.
The Long-Bell expedition attempts to find the source of the Red and Arkansas

Explanation:
The chronological sequence of the expeditions are given as follows-
1. Meriwether Lewis and William Clark were tasked with the exploration of lands west of the Mississippi River by the then-President Thomas Jefferson in 1804. The exploration of these lands was a follow-up of the Louisiana Purchase, the land deal between the US and France where the US acquired the west side of the Mississippi River.
2. The expedition under Captain Richard Sparks was another expedition commissioned by President Jefferson along the Red River in 1806. This expedition was to determine and collect data about the land, flora, and fauna of the lands still unfamiliar, particularly of the lands of the Native Indians.
3. In 1811, George C. Sibley went on an expedition to bring about improvements in the relationship with the Pawnee and Kansa tribes. He also wanted to discover the rumored Jefferson salt mountains. But rather, he found the salt mountains in the Northern Oklahoma salt plains.
4. In 1820, Maj. Stephen Harriman Long of the U.S. Army Topographical Engineers and Capt. John R. Bell went on an expedition alongside the western lands of Oklahoma. This expedition was determined to find the source of the Red and Arkansas Rivers.
