Management of geologic resources primarily addresses preserving unique geologic features such as paleontological resources, fragile easily eroded geological features, or scientifically important strata. Mineral development, as well as other surface‐disturbing activities, can alter existing geologic features by disturbing, or excavating soil and rock. Sections 4.5 Heritage and Visual Resources and 4.7 Special Designations in this chapter discuss associated impacts to geologic resources. Section 4.2 Mineral Resources discusses impacts to mineral resources.
