Test Dig Electrical Resistivity Testing Seismic Refraction Exploration

ST. HELENS AREA PRELIMINARY INVESTIGATION

Test Dig Sample Characteristics

Introduction: To help determine the extent of basalt bedrock and the degree of fracturing in the study area.

Electrical Resistivity Exploration

Electrical Resistivity Exploration

Seismic Refraction ExplorationAll of the bedrock velocities measured in this study exceeded 14,600 ft/sec.

Seismic Refraction Exploration

Rock would require preparation by blasting and efficient dredging of prepared rock would not be feasible by any means other than a large excavator type dredge.

Conclusions of Preliminary Investigations
