The line coming out of the well casing was 26" below the top of the casing. Which is 14" above the grade (ground level). Meaning the line is 12" too high. It needs 24" of material covering it, not 12".
I used an infrared heater to thaw the sand and rock, dug some out and repeated until I got to the line and voila, it thawed and the water flowed.
Richardson well drilling says there installers normally go 18" to 24" below grade. Fortunately, I left a small tree by the well (my witness).
The easy remedy is EPS insulation and another 6" of fill raising the grade of the area. If that doesn't do it, the hard fix is they pull the pump and relocate the line in the casing (at their expense).
I'm getting mellow in my old age, I'll go the easy route.
