Story

Researched 8 Oct 2026, fact-checked.

Hell's Half Acre began in 1930 as a platform set in the top of a 40-foot tree on the Bitterroot National Forest, in the Magruder Corridor.1,2 Sources disagree about what came next.1,2,3,4 The National Historic Lookout Register and Idaho Fire Lookouts date an L-4 cab on a 10-foot tower to 1940, while firelookout.com and an Idaho lookout history site put a 40-foot pole L-4 tower up in 1934.1,2,3,4 The current R-6 cab stands on a 10-foot concrete base, and the register, firelookout.com and Idaho Fire Lookouts all give 1960 as its build year.1,2,3 That history site adds that Dave Langley and a two-man crew built a cinder-block base with an R-6 cab in 1959, and a March 2, 1960 Ravalli Republic item reports that a new lookout house went up at the site.4

Idaho Fire Lookouts lists named staff from 1945 onward.2 The register says the lookout gets regular staffing during fire season.1 Mark and Rhett Moak staffed it every season from 1997 to 2016.2 The lookout has also been wrapped against nearby fires.2,4 In 2013 it was covered in fire-retardant material and the staff moved temporarily to Salmon Mountain.2,4 In 2017 it was wrapped again, and the staff were evacuated by helicopter.2,4

The register recorded the lookout on April 24, 2009.1 Idaho Fire Lookouts says the Moaks staffed it again in 2025.2

Idaho Fire Lookouts lists the lookout as drive-up and staffed today.2 The University of Idaho's Keeping Watch project places it in the Selway-Bitterroot Wilderness, along the Idaho-Montana line.5 A lookout interviewed for that project says this site can be driven to.5 The register says the view takes in the upper Selway River and the neighboring Frank Church River of No Return Wilderness, so the two sources name different wilderness areas.1,5 Because it is a working fire lookout in season, check with the Bitterroot National Forest before planning a visit.1,2

Where sources disagree

We show disagreements between sources instead of quietly picking one. If you know which is right, please tell us.

  • Sources disagree on the year it was built.

    • NHLR: 1960
    • firelookout.com -- Rex Kamstra's Forest Fire Lookout Page: 1934

    Sources give different build years. Often one counts the first lookout on the site and another the structure there now.
