==Summary==
These surveyors' monuments, and witness stones which locate them, played a vital role in the survey of public lands in Nebraska, Kansas, Colorado, South Dakota, and Wyoming. A cast iron monument, located on a bluff above the Missouri River in Richardson County near present-day Rulo, marks the initial point for the survey. It was set in place on May 8, 1855. An 1856 red sandstone monument marks the intersection of the sixth principal meridian and the fortieth degree of the north latitude base line (the point where present-day Thayer and Jefferson counties, Nebraska, and Washington and Republic counties, Kansas, meet). The monuments remain major reference points to the present day in the rectangular land survey system. Broken off and reburied several times, the stone monument was most recently unearthed in 1986 by surveyors from five states who were sponsored by the Professional Surveyors Association of Nebraska.
