Now that is some awesome finds, especially for Texas. I live in Texas too (Clyde, by Abilene) Few people, including Texans, know that there were civil war out posts in a line all the way down to San Antonio. I found a map that shows this, and it stunned me, cause we never learned this in school.
I have a cousin that lives on the Little Colorado and he has found some very interesting stuff.(possible some buried cannons) It is too hot for digging right now.
