I don't remember where I found this list, sorry about the formatting, wish I could credit the source, or just link to it:
“The men who harvest big timber on Pacific Northwest forestlands have, through the years, developed a distinctive language all their own. While some traditional logging terms, methods and items, such as the old "misery whip" shown above, have been mechanized or replaced, much of the language remains.
Some of these terms stem from the Maine logging of 150-200 years ago, and others date back to the Lake States and others to the South. But, most were born in the woods of Washington, Oregon, Idaho, and California.
Several historic pictures accompany this material and are intended to be reminders of the past. Modern loggers no longer live in camps, eat in cookhouses, or use railroads. Likewise, several terms in this booklet are also past reminders and are not necessarily used today by all loggers. But the logger's language is unique, and it is his.”

In pine country, they were also known as packsackers. With the years, "Gypsy" developed into the euphemism "Gyppo."
