James, this is in Rusk County, south of Longview, Texas and east of Tyler.
You mentioned one of my favorite areas of Texas. We have been to the Frio River several times and are planning another trip there in a year or two. Utopia is where we go to buy our meat to barbeque after a long day floating the river on tubes. The best steak I have ever eaten came from the little grocery store there in Utopia. I grilled it over mesquite wood I collected on the way back to the cabin from Utopia. I wish I could get beef that good here.
Jludwig, it is definitely iron ore, through and through. There is no gypsum anywhere around here that I know of except about 25 miles east. But everything on this property is iron ore for sure. I have not even seen a rock of another color. I wish I did have other kinds as I plan to build several rock retaining walls and the color change would be more attractive.
