Forty miles west of Casper (US 20/26) you will find Hell’s Half Acre. It’s actually 320 acres of deep ravines, rock formations, and eroded earth. The earth is relatively flat until you approach this area. It will have you saying “wow!”
The Indians drove herds of buffalo into this area for slaughter. Arrowheads and buffalo bones have been found here.
The location had several names before it was labeled Hell’s Half Acre. It was also known as “The Devil’s Kitchen”, “The Pits of Hades”, and “The Baby Grand Canyon.” A lost cowhand found it and thought he was at Hell’s Half Acre, an area southwest of Casper full of alkali and bogs.
The 1997 Starship Troopers was filmed here. This area was the fictional planet Klendathu.
It was nominated for an Academy Award for best visual effects in 1998.
