Assessment of the Alluvial Sediments in the Big Thompson River Valley, Colorado - USGS_DDS-66
Listed in NASA Earthdata CMR
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.
Description
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 gross stratigraphy of the alluvium.
