Texas Soil Surveys (University of North Texas. The Portal to Texas History)
“The Texas Soil Surveys demonstrate early scientific thought regarding soil classification and use. Each survey consists of a soil map and separate book. The maps show many cultural features in the landscape such as businesses, churches, schools, mills, gins, and ferries. The collection embraces all Texas county and reconnaissance soil surveys completed prior to 1950.” The collection is part of the University’s Portal to Texas History, which “offers students and lifelong learners a digital gateway to the rich collections held in Texas libraries, museums, archives, historical societies, and private collections.”
