Derivative Map of the Geologic Materials and Hazards in the Eastern Half McGrath Quadrangle, Alaska
Description
This map illustrates the potential near-surface sources of various geologic materials that may be useful for construction. Field observations indicate that each geologic unit has a definite composition or range of composition wherever that unit is found. Therefore, the presence of materials is interpreted from the distribution of geologic units on the geologic map of this quadrangle. This map is generalized and is not intended to show exact locations of specific materials. The map also addresses some of the principle geologic hazards that may be associated with the deposits based upon their general physical properties and conditions that are characteristic of their depositional environment.
