Possible Adjustment FactorsBank Materials
Cobble decrease the category by one unless the mixture of Sand/Gravel is over 50%
Gravel- adjust the values up 5-10 pts depending on sand composition
Bedrock is always Very LowBoulders are always Low
Sand- adjust the values up 10 ptssilt/clay- no adjustment
