(visited by Ross Finlayson)

14-Apr-2024 -- While driving westward along Interstate 40 from Oklahoma City to Amarillo, I was interested in making a detour to visit this point, as I was intrigued by Joseph Kerski’s description from September 2022. (Also, I had yet to visit any points along the 100 Degrees West line of longitude.) From the small town of Erick, Oklahoma, I quickly drove South on (wide, paved, well-maintained) Oklahoma Highway 30. I then turned West onto exactly the opposite type of road - narrow, dirt, barely maintained - that ran East-to-West (just South of 35 Degrees North), then crossed into Texas and turned North onto a (similarly bad) dirt road that passed just West of 100 Degrees West. I was nervous about getting stuck (or getting a flat tire) in such a remote area; I would definitely advise against driving on these roads in wet conditions. I parked on the side of the dirt road at about 35 Degrees North, about 0.46 miles West of the point. (This appears to be about the same place that Joseph Kerski parked.)

After crossing an annoying barbed wire fence, I embarked on what turned out to be an easy hike (about 1/2 mile each way) to the point. The point lies in a small ravine, just on the eastern edge of a small creek - Coon Creek - that happens to be close to the Texas-Oklahoma state line. (The River Runner website shows that water from this creek continues East into Oklahoma, then turns South to join the Red River, which once again follows the Texas-Oklahoma state line, eventually ending up passing through Louisiana to the Gulf of Mexico.)

Several of my recent visits to Degree Confluence Points in the Texas-Oklahoma-Arkansas area had been thwarted by strong winds, so I was pleased to encounter calm conditions today as I flew my drone Southwards along the state line. Here is a remote-controlled aerial video of this confluence point.

Afterwards, I continued North and West along some more sketchy dirt roads, eventually rejoining paved roads, to reenter Interstate 40 at the town of Shamrock Texas (where I saw its famous old Route 66 Conoco gas station).
