Alaskan Geologic Field Notebooks with Sketches and Observations

3,600 original field notebooks contain geologic observations from USGS geologists working in Alaska. Records include field stations, sample numbers, rock descriptions, terrain conditions, and outcrop sketches. Some notebooks also report daily weather, topographic measurements, and personal accounts from early explorers.

Use Cases

• Analyze rock type descriptions and terrain conditions to map regional geology.
• Study field station locations and sample numbers for resource exploration planning.
• Examine outcrop sketches and topographic measurements for historical landscape reconstruction.
• Review daily weather and camp life notes for historical climate or expedition context.

Strengths

• Contains 3,600 original field notebooks, providing a substantial primary source collection.
• Records include multiple data types: text descriptions, sketches, and geospatial station data.
• Preserves first-hand observations from USGS geologists, offering direct scientific documentation.

Limitations

• Access is restricted; notebooks may be viewed only by written request or appointment.
• Potential geographic bias, as coverage is limited to USGS field work areas in Alaska.
• Data format and consistency are unknown, likely requiring manual review and transcription.
