The Michigan Geological Survey received a donation of geolographs from multiple industry members (Jimmy Miles, Jack Mortensen, and others) . Most are from the 1970’s. The logs record the drill bit penetration rate through the rock as the well was drilled for oil/gas. The red line on the logs are the penetration rates. Footages are calculated and handwritten on the logs by the mudlogger. This information is helpful in observing which lithology the bit is drilling through according to the ease and short time vs more difficult and longer times of drilling through a formation.
This data release is a collection of data and field notes documenting snow and ice changes on South Cascade Glacier, Washington, USA. The field records relate to glaciological research and reflect evolving interpretations of glacier mass balance, climatology, hydrology, and other glacier-related research conducted at the site between 1957 to 2022 in association with the USGS Benchmark Glacier Project. Notebooks have been scanned in their entirety in PDF format. The USGS Benchmark Glacier Project has monitored targeted mountain glaciers across North America since research was initiated at South Cascade Glacier in 1957. Data from the five benchmark glaciers located in Alaska, Washington, and Montana, provide continental-scale...
