Camping near this location on September 10, 1825, the U.S. survey team remained through September 21 waiting for a courier with information from the U.S. Government on how to proceed further. Believing this point to be west of the 100th meridian and south of the Arkansas River, surveyor Joseph Brown mistakenly identified the area beyond as Mexican territory, where the survey team had no permission to enter. When no such information arrived, the team divided: commissioner George Sibley, surveyor Brown, interpreter William Williams, nine men, and Sibley's servant Abram continued with the survey, while the other two commissioners, Benjamin Reeves and Thomas Mather, with secretary Archibald Gamble and the rest of the team, returned to Missouri.
