The location of the rock outcrop pictured above is in Victorio Canyon, Texas, just south of Guadalupe Mountains National Park. The color part of the image was scanned from a Pentax medium format print and digitally matched with a 3-D laser scan acquired by an Optech ILRIS 3-D lidar (light detection and ranging) scanner. When the photograph was blended with the 3-D laser model, (the black and white image) the result was a spatially correct 3-D photograph that enables geologists to quantitatively examine the ordered layering of strata directly from the 3-D model. This is especially important when trying to relate geology we observe on the surface of the Earth to that which we cannot observe directly in the subsurface.
