State line oddities: five border quirks worth photoing

April 21, 2026 · 4 min read

Five quirky state line markers with exact GPS or addresses, parking tips, and family-friendly access for quick photos.

You want weird border photos without a wild goose chase

You’re rolling down the interstate, kids counting plates, and someone yells, “Did we cross the state line yet?” Here are five quirky, easy-to-stop border spots—each with coordinates or an address and tips for finding them fast.

Four Corners Monument: yes, you can stand in four states at once

• What it is: The only point in the U.S. where four states meet (AZ/CO/NM/UT). The plaza sits inside a Navajo Tribal Park.
• Exact location: 36.998976° N, -109.045172° W per the tribal site’s published coordinate and common geodetic reporting ([Navajo Nation Parks]). The National Geodetic Survey explains how the monument’s surveyed placement defines the boundary in practice ([NGS — National Geodetic Survey]).
• How to find it: Follow the signed park road; the Navajo Nation notes that GPS and cell service can be unreliable in the area, so use the directions on the park page and don’t count on turn‑by‑turn once you’re close ([Navajo Nation Parks]).
• Family photo logistics: There’s a marked plaza with a medallion and state sectors. Expect a brief line for the “one foot in each state” shot.

Texarkana’s half-and-half courthouse: Arkansas on one side, Texas on the other

• What it is: The U.S. Post Office & Federal Courthouse that straddles the AR/TX line, parked right in the median of State Line Avenue.
• Exact photo spot: 500 N State Line Ave, Texarkana (the building’s bi‑state address). Visitor materials flag the median in front as the classic “half in Texas, half in Arkansas” shot ([DowntownTX]).
• How to find it: It’s downtown with easy street parking and a wide median.
• Family photo logistics: Sidewalks, crosswalks, and a big facade make it simple to frame your picture without dodging traffic.

Tri-States Monument (NJ/NY/PA): a granite marker by the Delaware

• What it is: The point where New Jersey, New York, and Pennsylvania meet—often called Tri‑State Rock—near Port Jervis.
• Exact location: 41°21'26.18" N, 74°41'41.00" W on the NGS datasheet for the monument/witness setup (WGS84) ([NGS LY2604]).
• How to find it: Approach from Port Jervis city streets and walk a short path toward the river. The NGS record documents both the primary marker at the point and a nearby witness monument in town.
• Family photo logistics: The riverside granite marker is accessible for photos, but the literal tripoint can sit in the river channel depending on water level. If the water’s high, use the witness monument and the bank marker for the picture.

OKARMO Corner: a three-state selfie without leaving the shoulder

• What it is: The Oklahoma/Arkansas/Missouri tripoint monument.
• Exact location: 36.49950° N, -94.61788° W, right by the junction of MO‑43, AR‑43, and OK‑20 ([Mapcarta / OpenStreetMap]).
• How to find it: Pull off on the paved shoulder near the highway junction; the stone and sign cluster are visible from the road.
• Family photo logistics: No hike, no fees, just a quick hop out. Keep kids close—this one’s roadside, not a park.

Mason–Dixon oddities: hunt the survey stones and the Star Gazers’ Stone

• What it is: Mason and Dixon’s 1760s survey left a trail of original stones and later granite markers defining the Maryland–Pennsylvania–Delaware boundaries. Two photogenic features: the Star Gazers’ Stone (their temporary observatory point) and the graceful curve of Delaware’s 12‑Mile Circle/Arc Corner monuments.
• Exact reference latitude: The west line sits at roughly 39°43'19.92216" N per state/local documentation of the parallel ([Chester County]). This is a legal survey line; individual stones can sit slightly off the “mathematical” ideal because the accepted monuments define the boundary in practice.
• Star Gazers’ Stone location: The named observatory site is documented in Embreeville, Pennsylvania, with a specific geotag on its landmark page ([Wikipedia — Star Gazers’ Stone]).
• Access reality check: State and local guides note that some stones and tripoints in this system are on or near private land; get permission or use public‑park approaches where indicated ([Delaware Geological Survey PDF]).
• How to find it: Use local park approaches where available, and confirm directions from county or state resources before you go—older coordinates can shift on modern maps if datum isn’t noted.
• Family photo logistics: The Star Gazers’ Stone and several public‑park approaches to boundary markers make for easy, low‑stress photos. Skip anything posted or fenced.

Quick planning notes so you don’t get skunked at the line

• Verify the source of any coordinate before you go. Tribal park pages and NGS — National Geodetic Survey datasheets are reliable; random reposts often aren’t.
• Don’t trust cell service at remote markers. The Four Corners page explicitly warns that GPS/cell can be spotty near the plaza (Navajo Nation Parks). Save an offline map and the official directions.
• Respect property lines. The Mason–Dixon materials note that some markers sit on private land; use public approaches or get permission (Delaware Geological Survey PDF).
