资源简介：
These notebooks are the original field records of geologic observations made
by USGS geologists working in Alaska. They contain field stations, sample
numbers, rock types and descriptions, terrain conditions and outcrop sketches.
Some also report topographic measurements, daily weather, and camp life. A few
personal diaries of the early explorers are preserved.
The notebooks may be viewed by written requests or appointment only. Access to
certain materials may be restricted for non-government employees. Microfilm
for these records is stored in Menlo Park, California. The data consists of
3,600 notebooks.
