   • 1929, Soil Survey of Potter County, Texas, US Bureau of Chemistry and Soils, page 44:

     According to local well drillers, in wells drilled on the high plains a few hundred feet back from the caliche escarpment or in other locations on the high plains in this area no hard caliche or white layer, such as would characterize a soft layer of high lime-carbonate content, is generally reached at a depth corresponding to the elevation of the caliche escarpment.

   • 1985, Julie Behrend Weinberg, Growing Food In the High Desert Country, page 17:

     Having a layer of caliche at depths of 16 inches and less really puts a damper on the garden site. The caliche does not allow roots to penetrate it (tree roots often take 10 years to break through a caliche layer) nor does this mineral allow water to drain.
