- Description:
- Derived from 1:250,000-scale USGS HUC 8 boundaries, this dataset represents the soil boulder fraction for the western USA. A weighted average was created for each HUC 8 watershed using approximate EMAP physical habitat substrate criteria. The values are expressed as percent by weight.
