Excerpt from Geological Survey of Alabama, 1892, Vol. 2: Bulletin No. 2 on the Phosphates and Marls of AlabamaThe whole thickness of the strata of the Tertiary Formation of Alabama, occurring in the vicinity of the two rivers, is between 1620 and 1700 feet. This estimate is based upon actual measurements, except at one or two horizons, and even in these places we are able to give close estimates of the thickness of the strata not measured.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
