Preston Monument: Difference between revisions

Southern faces of tourist version of the Preston Monument. The original Preston Monument may have been replaced by this modern granite marker.

The Preston Monument is the common name for a stone marker at the tri-point (the place where three states meet) of Oklahoma, Colorado, and New Mexico. It is named after Levi S. Preston who surveyed a portion of the New Mexico–Colorado border in 1900. The marker that bears his name may be an earlier monument placed by Richard O. Chaney and William W. Smith.

Preston evaluated and established several monuments during his survey of 1900. He was contracted on October 25, 1899 with the United States General Land Office to survey the eastern New Mexico and western Texas borders and compare his results with prior surveys.

Besides determining the boundaries between Texas and New Mexico, Preston was tasked with determining the true location of (1) the northwest corner of Texas, a point of some contention and believed to be lost, (2) the tri-point of Oklahoma, Texas, and New Mexico some 2 miles to the east, and (3) the tri-point of Colorado, Oklahoma, and New Mexico, some 34 miles north, the tri-point bearing his name.

In 1902, Preston's success in establishing the northwest corner of the State of Texas was published in a bulletin of the U.S. Geological Survey. He was lauded for his "zeal, intelligence, and faithfulness."

Solving the contentious Texas-New Mexico border dispute was not his only legacy. The tri-point monument bearing his name would be called upon in the Supreme Court Case of New Mexico v. Colorado, 267 U.S. 30 (1925) to help establish the permanent border between New Mexico and Colorado.

Tri-point of Oklahoma, Colorado, and New Mexico

The tri-point marker for Oklahoma, Colorado, and New Mexico is at an elevation of 4,444 feet at 37.000154°N 103.002362°W / 37.000154; -103.002362. The current marker is of a modern concrete rectangular base with an erect, granite stone pillar. An 1881 marker is nearby which matches the description of the one erected by Richard O. Chaney and William W. Smith in the fall of 1881 when they surveyed the Cimarron meridian, the western border of Oklahoma.

37th parallel north and 103rd meridian west

The tri-point for Oklahoma, Colorado, and New Mexico is supposed to be the intersection between the 37th parallel north and the 103rd meridian west. This point had been located by several surveys before 1900. None of them had agreed. The State of Texas had decided to enter the Union as a slave state, and therefore had been forced to limit its northern extent to 36° 30" north. Areas to the north of the Texas panhandle had become part of "No Man's Land," now the Oklahoma Panhandle. The establishment of the borders of the land eventually known as Oklahoma had required a western limit of 103° west longitude, which is the same as the Texas-New Mexico border. Therefore, the southwest corner of Oklahoma and the northwest corner of Texas should be the same point, and the 37°N, 103°W point should be due north and around 34 miles distant.

By 1900, it had become obvious that the original Texas-New Mexico border was a few miles west of the intended 103° meridian. The 1881 surveyors for the Cimarron meridian, Richard O. Chaney and William W. Smith, had set their meridian very close to modern 103° meridian and essentially ignored the erroneous Clark 103° meridian to the south. They also ignored the Macomb and Johnston markers to their west.

All of these were supposed to mark 37°N, 103°W:

• Johnston monument (1857) by John H. Clark (also reused by John J. Major in 1874 for the New Mexico border)
• No marker (1859) by John H. Clark, but its location was established by Preston in 1900 from Clark's 103° meridian
• Macomb monument (1859) by Capt. J. N. Macomb, supposedly the NE corner of New Mexico
• Darling monument (1868) was in the same place as Macomb's but rebuilt by Ehud N. Darling
• Major's monument (1874) was Darling's and Macomb's monument, rebuilt like Macomb's original by John J. Major
• Chaney monument (1881) by Chaney and Smith, used for the Cimarron meridian
• Preston monument (1900) by Preston. He found all of the above previous monuments and measured to them. This is actually Chaney and Smith's monument for the Cimarron meridian, and so it bears an 1881 date. May still be extant.
• The new monument (unknown). There is a granite marker for tourism located here. Still extant.

Northwest corner of Texas and the 1900 survey

John Major searched for the lost northwest corner of Texas on his 1874 survey, but did not find it. He actually found the benchmark stone that was intended for the corner, but it had been repurposed at a survey station about 8 miles away for a gravestone.

After much searching, Preston found the old 1859 John H. Clark corner in 1900. He laid a stone marker where he had found two previous posts, the earlier of which he was convinced was the original marker from 1859, stating:

At this northwest corner of the [Capital Land and Cattle Company] XIT pasture fence, I remove wire fencing, dig up the corner post, which I find set 18 inches in the ground, and set on top of the rotted stump of an old cedar post. Excavating carefully around this old stub, I find the bottom of it at 26 inches below surface of ground, and remove a segment of the old post 8 inches in diameter and 8 inches long, greatly decayed and reduced almost to a dry pulpy ash. The dark mould and pieces of decayed cedar indicated that the original post was about 10 X 12 inches in diameter at bottom. This old cedar post could easily have been in the ground more than the eighteen years since 1882, and very likely for ten years longer.

Thus, Preston re-established the northwest corner of Texas that had been in use since the incomplete 1859 survey. He continues:

I set a sandstone 60 X 12 X 10 inches 36 inches in the ground for the northwest corner of the State of Texas, marked

"N.W. Cor.
---------
  Texas"

on east; "N. M.," on east; "1859," on south, and "1900," on north faces.

The marker, if still intact, is apparently under the road surface of U.S. Route 56.

Texhomex at the tri-point of Oklahoma, Texas, and New Mexico

Richard O. Chaney and William W. Smith established the Cimarron meridian in 1881, setting the monuments at two tri-points on the western edge of No Man's Land before Oklahoma was admitted as a State. The southern one would become known as Texhomex. It was re-established and checked by Preston in 1900. Its location was instrumental in finding the northwest corner of Texas.
