Whitehall Geogroup, Inc.

 Whitehall GeoGroup, Inc. (WGI) utilizes an integrated approach to earth science in a diversity of consulting projects including minerals remoteness work, geological review of properties, geologic mapping, hydrostratigraphy, oil and gas exploration, reservoir characterization, and minerals evaluation.

       Our continued efforts in research of continental sedimentation/ stratigraphic analysis have enabled WGI to provide cutting-edge expertise in these areas. We currently have projects focusing on high-elevation Tertiary sedimentation, isotopic age constraints on Tertiary strata, and the relocation of vertebrate paleontologic age-control locales.

AREAS OF EXPERTISE

(Contact whgeol@gmail.com for more information on Whitehall Geogroup, Inc.’s services.)

CONSERVATION EASEMENT MINERAL REMOTENESS EVALUATION – WGI offers field work and report preparation services for mineral remoteness uations.  We have completed over 327 minerals remoteness projects covering portions of Montana, Idaho, North Dakota, and Wyoming properties for various conservation organizations and private entities.

GEOLOGICAL REVIEW OF REAL ESTATE PROPERTY – WGI provides field work and report summaries of properties for private entities in order to meet due diligence and county planning regulations.

PALEOSOL INTERPRETATIONS – A primary focus of WGI’s research  is paleosol identification in continental strata.  WGI’s current research is focused on calcic paleosols, particularly calcic pedocomplexes.

CONTINENTAL SEDIMENTATION/STRATIGRAPHIC ANALYSIS – WGI research is directed towards the delineation of continental sedimentation patterns by various geological/geophysical techniques, and the development of sequence stratigraphic techniques as applied to continental deposits.

An overview of WGI’s work with continental strata in southwestern Montana is shown in the following YouTube video:

GEOLOGIC MAPPING – WGI specializes in geologic mapping of Cenozoic basin fill in the western United States. We have also recently completed numerous 1:24,000 scale geologic maps for geologic baseline studies of properties throughout western and central Montana. Some of our recent projects in Montana include:

Toston-Townsend, Montana area– WGI has compiled a geologic map of the Toston-Townsend valleys, southwestern Montana.  This map includes the Sixmile Creek type section, and is available at the 1:100,000 scale (metric topographic).  WGI is continuing geologic mapping in this area.   Our emphasis is on mapping the stratigraphy/structure of Cenozoic deposits.

Rocker-Ramsey, Montana area – WGI has recently completed a geologic map of the Rocker – Ramsey area, southwestern Montana.  This map is available at the 1:100,000 scale (metric topographic), and covers part of the upper Clark Fork Superfund area.

Sage Creek – Upper Ruby – Blacktail Valleys, Montana – WGI has completed a geologic map of the Sage Creek – Upper Ruby – Blacktail valleys, southwestern Montana.   This map is available at the 1:100,000 scale (metric topographic).  A report accompanies this map; the report includes unpublished age dates (radiometric/vertebrate land mammal ages) and lithologic descriptions of the Cenozoic strata.

GIS EARTH SCIENCE APPLICATIONS – A recent WGI project is the compilation of vertebrate fossil sites and their associated fossil assemblages found on public lands within Beaverhead and Madison counties, Montana.   The fossil site compilation is in ArcView 3.2 format, and was completed for the Bureau of Land Management Dillon Resource Office in Dillon, Montana.  Project components include several 100k land grids, associated 100k land ownership grids, and fossil assemblage/ general collection database files.  

HIGH RESOLUTION SEISMIC REFLECTION/ REFRACTION DATA ACQUISITION AND INTERPRETATION – WGI performs shallow seismic data acquisition/interpretation.   Our work in this area has been focused on developing acquisition parameters and interpretation techniques for Cenozoic continental basin-fill.

VIRTUAL GEOLOGY FIELD TRIPS – WGI is currently developing virtual geological field trips in a multimedia cd-rom format.  Our first field trip encompasses the Whitehall, Montana area. Our second virtual field trip is on Southwestern Montana Geology. 

CURRENT PROJECTS

  • Tertiary chronostratigraphy and paleosol-trace fossil associations, Pipestone Springs, southwest Montana.
  • Southwestern Montana Tertiary volcanic ash and tuff age analyses, with emphasis on relationships to calcic paleosol pedocomplexes, intervalley stratigraphic correlation, vertebrate fossil paleogeography, and Eocene/Oligocene boundary delineation funded by the Museum of the Rockies, Bozeman, Montana and the Raymond M. Alf Museum, Claremont, California.
  • Tertiary geology and vertebrate paleontology of the Lima-Sage Creek area, southwestern Montana.
  • Relocation of Earl Douglass’s fossil vertebrate localities found during 1894-1896, Madison Bluffs, southwestern Montana.
