Explanation:

The Sparks Expedition, also known as the Freeman-Custis Expedition or Red River Expedition was a scientific expedition that explored the Southwestern United States. The purpose of it was to explore the Red River from the Mississippi River with the hope of finding a possible trading route to Santa Fe.
