Mount Sopris is a twin-summit mountain in the northwestern Elk Mountains range of the Rocky Mountains of North America.The prominent 12,965-foot (3,952 m) mountain is located in the Maroon Bells-Snowmass Wilderness of White River National Forest, 6.6 miles (10.7 km) north by northeast (bearing 30°) of the community of Redstone in Pitkin County, Colorado, United States.
Choker setters at work attaching a log to a skyline in Cowlitz County, Washington (October 1941). A choker setter or choke setter is a logger who attaches cables to logs for retrieval by skidders or skylines.
A log driver using a peavey. A cant hook, pike, or hooked pike is a traditional logging tool consisting of a wooden lever handle with a movable metal hook called a dog at one end, used for handling and turning logs and cants, especially in sawmills. A cant hook has a blunt end, or possibly small teeth for friction.
Modern resistivity logging tools fall into two categories, Laterolog and Induction, with various commercial names, depending on the company providing the logging services. Laterolog tools send an electric current from an electrode on the sonde directly into the formation. The return electrodes are located either on surface or on the sonde itself.
The tool itself initially consisted of a radioactive source and a single detector, but this configuration is susceptible to the effects of the drilling fluid. In a similar way to how the sonic logging tool was improved to compensate for borehole effects, density logging now conventionally uses 2 or more detectors. In a 2 detector configuration ...

The accuracy of modern compressional and shear sonic logs obtained with wireline logging tools is well known now to be within 2% for boreholes that are less than 14 inches in diameter and within 5% for larger boreholes. Some suggest that the fact that regular- and long-spaced log measurements often conflict means these logs are not accurate.
A special tool designed specifically for underbucking facilitates the job of cutting from the ground upwards. The underbuck tool is driven into the section of the log which is considered to be least likely of moving once the cut has been successfully made. The crosscut saw's backside rides along the pulley that rests on the bar driven into the log.
