Geoscience

Geoscience is often a crucial element for efficient resource management of natural resource projects. Bristlecone-Geo assists landowners, extractive resource industry, local government, land appraisers, and land trusts through providing qualified geoscience research, mapping, and reporting services. Keeping the audience in mind, our reports are written to provide the rationale necessary to substantiate informed decisions for decision makers.

From recent mapping to historic map conversions, Bristlecone-Geo also crafts geologic maps, cross sections, stratigraphic columns, and other illustrations for baseline documentation and mineral assessment reports.

Bristlecone-Geo has prepared dozens of geoscience, mineral assessment reports, and remoteness letters for baseline studies. Our reports are prepared in accordance with classification systems developed by the BLM, USFS, and USGS by a Certified Professional Geologist.

Geologic Maps & Illustration —

Together with Pangaea Geospatial, Bristlecone-Geo has provided ongoing geologic map support to the Colorado Geological Survey (CGS) since 2008. Utilizing authoring geologist’s field notes and sketches, project elements include the development of geologic cross sections, correlation of map units, and other illustrations. CGS geologic map projects are partially funded by the USGS National Cooperatibe Geologic Mapping Program. Beginning in 2020, we have transitioned map development to the USGS Geological Map Schema (GeMS), a process which standardizes digital geologic map publications across the United States.
