Hell's Half Acre
Panned by critics but enjoyed by audiences, Starship Troopers (1997) took over Hell's Half Acre – which is really more like several hundred acres – 40 miles northwest of Casper in 1996. Pre-production crews scouted more than 22 states before settling upon this site, formerly a Native American buffalo hunting ground. It wasn't just Wyoming scenery that ended up being used, either; casting calls went out in Riverton and Cheyenne for 17- to 30-year-olds in "excellent physical condition." Some 350 extras were hired.

More than a decade after Starship Troopers was filmed, little evidence of Whiskey Outpost, A Company Base Camp, Port Joe Smith, Tango Urilla Base Camp and Klendathu exists when looking down from the canyon's rim. If you manage to get permission to walk down into the canyon, though – and rattlesnakes are still every bit as present now as they were when filming, so watch your step – you can find everything from spent bullets to bottle caps stuck in the mud.

Hell's Half Acre is managed by Natrona County Parks and is right off U.S. 20/26.
