I'm not there now. But there was always a fence but it was easily overcome. Since Santa Theresa and Sunland Park are connected to El Paso, it only makes sense to continue the wall past this NM area. A little farther west begins vast desolate desert which is owned by BLM (Bureau of Land Management) and private ranches for cattle grazing. However, this land is also an area of incursion into the US. New Mexico is a poverty state, run by Democrats (go figure), 2nd poorest state in the US, so they would NEVER build a wall for two reasons: 1) they are against controlling immigration and 2) they have no frigging money. Texas, knowing that if the illegals can't come through the Texas wall will just go right around it where it ends in Santa Theresa, so it only makes sense that to not continue the fence would negate the effect of the wall through El Paso. In El Paso, most of the year the Rio Grande is dry because it is dammed up at Elephant Butte man-made lake. In the Spring, Elephant Butte releases water for irrigation and flows until the fall but it is usually crossed easily by walking across or wading. Some areas are treacherous.
