Geoscience Support

Senior-led geoscience expertise for complex terrain, watershed, and instability concerns
across British Columbia.

Not every terrain or stability issue fits neatly into a predefined assessment category.

Some projects require broader geohazard context. Others require focused investigation. In many cases, clients need experienced professional input early.

Third Rock Geoscience provides flexible, terrain-focused geoscience support grounded in BC field experience and professional accountability.

Beyond Standard Assessments

While Terrain Stability Assessments (TSA) and Karst Field Assessments (KFA) form the core of our work, we also support clients with:

  • Landslide investigation and characterization
  • Sedimentation and erosion assessments
  • Terrain Ecosystem Mapping (TEM) input
  • Watershed-scale terrain overview
  • Site-specific geohazard evaluation
  • Road construction and deactivation revie
  • Post wildfire assessments
  • Terrain training classroom based and/or in the field based
  • Licensee Terrain Program Reviews
  • Expert witness representation

These engagements range from high-level overview mapping to detailed field investigation.
The scale depends on the question being asked.

Professional Accountability

All geoscience support provided by Third Rock Geoscience is conducted to guideline standards of the Engineers and Geoscientists BC (EGBC).

Professional accountability means:

  • Clear scope definition
  • Transparent reasoning
  • Defensible documentation
  • Consistent recommendations

Where formal reporting is required, documentation reflects regulatory expectations. Where advisory input is requested, guidance is practical and proportionate.

Landslide Investigation

Landslides are destructive.

When slope failure occurs—or when movement indicators raise concern—timely professional assessment matters.

We evaluate:

  • Failure mechanism and contributing factors
  • Soil and slope geometry conditions
  • Hydrologic influence
  • Construction or disturbance role
  • Downslope impacts
  • Guidance and confidentiality to clients when regulatory questions arise

Understanding why a slope failed informs both remediation and future operational planning.

Where appropriate, findings are integrated into broader terrain management strategy.

Sedimentation & Erosion Assessment

Sediment transport can be driven by subtle changes in drainage or disturbance.

We assess:

  • Erosion source identification
  • Flow concentration points
  • Connection to downslope resources (e.g fish-bearing systems, private property, water intakes, major transportation corridors)
  • Transport energy and attenuation features
  • Operational mitigation options

As with terrain stability, sediment delivery potential is not defined solely by distance. Real-world hydrology and landscape context inform our conclusions.

Terrain Ecosystem Mapping (TEM) Support

Terrain and ecosystem characteristics are interconnected.

We provide terrain-focused input that supports broader mapping and planning initiatives (e.g. phase 1 environmental assessments)  ensuring that slope stability considerations are integrated alongside ecological values.

Our experienced team of professionals provides accurate classification and interpretation.

Watershed & Overview Assessments

Some projects require a broader lens.

Watershed-scale or overview terrain assessments may evaluate:

  • Regional slope sensitivity
  • Cumulative disturbance effects
  • Drainage network characteristics
  • Instability pattern recognition
  • High-level risk zoning

These assessments are conducted at appropriate mapping scales and provide context for more detailed site-specific work.

Overview does not replace field validation—but it guides it.

Early-Stage Professional Input

Many terrain issues benefit from early discussion before formal assessment is required.

We frequently provide:

  • Preliminary opinion on slope sensitivity
  • Early alignment development review
  • Professional input during project scoping
  • Risk identification prior to  resource extraction

Early engagement can prevent avoidable redesign or regulatory friction later.

Consistency from Field to Final

Whether conducting a formal Terrain Stability Assessment or a targeted geohazard review, our recommendations made by experienced professionals ensure  consistency from initial field observation through final documentation.

Clients can confidently move forwards with their projects. Our internal review process ensures alignment and clarity before deliverables are released.

Discuss Your Project

If your project involves steep terrain, slope instability, sediment risk, watershed sensitivity, or complex geohazard questions, early professional input supports safer operations and defensible decisions.
