Look into a job at a federal land management agency, and then join the fire “militia”. At my office about half the people are “red carded” which means they are qualified to support large incident response. The pay is your regular job pay, regardless of what job you do on a fire. And then you get paid overtime at time and a half, and they recently added incident response premium pay (look it up, for me it’s about $188/day). You go out for generally at least two weeks straight, staying in a large “camp” that has food, showers, some even have laundry services. Most people camp in tents, but there are also some awesome overland rigs that people bring. An assignment can be 14 to 21 days, then three days paid leave, then back to another assignment. You can turn down assignments if you don’t want to be gone all summer.

You’ve asked about pay a lot. Look at the GS pay scale hourly rate. That’s how much federal employees make. On a 14 day assignment, you are getting up to 144 hours of overtime in two weeks, plus the incident response premium pay. If you do a job that’s hazardous, like firefighting, you get an additional 25% bump.

There are all sorts of jobs on a federal fire, finance, planning, ops, gis, public info, driver, safety, camp manager, etc etc etc. https://iqcsweb.nwcg.gov/sites/default/files/inline-files/Position_List_Website_2.xlsx
