Assessment of the alluvial sediments in the Big Thompson River Valley, Colorado
To obtain subsurface geologic information about the alluvium in the Big Thompson River valley, S-wave refraction data were collected along three roads that cross the valley. The refraction data were used to estimate velocities and thickness for a layered-earth model; from these models, three cross sections of the river valley were constructed. These cross sections show the thickness and the gross stratigraphy of the alluvium.
