It’s what wildlife biologists have been observing for some time now: The plague has come to South Dakota’s prairie dog towns.
It starts with one family member showing signs of illness then another gets sick and another, before long most of the town is dead or dying.
Since about 2007 sylvatic plague has ravaged prairie dog colonies across western South Dakota. It started in the southwestern corner of the state and began slowly spreading north and east, causing colonies to nearly die out. Until recently plague hadn’t been found in the Fort Pierre National Grassland.
The linear slot HORD series diffusers are fabricated using 14 gauge aluminum or 20 gauge stainless steel to suit project requirements. The diffuser face is attached using spring-loaded quarter-turn fasteners for easy removal and access to internal surfaces for cleaning.
We wanted to share this cool video that Illustrates one of our installations of the rigid outdoor ductwork system with R-12 insulation from THERMADUCT.

Custer State Park is known for its free-ranging bison herd. With some 1,500 animals, it is one of the largest bison herds in the world. Pronghorn, deer, elk, mountain goats, bighorn sheep, mountain lions, burros, prairie dogs, coyotes, eagles, and wild turkeys are other residents of the park’s variety of habitats. The 18-mile (29-km) Wildlife Loop Road offers views of the animals, and bison often stop traffic as they cross. The Needles Highway is a twisting 14-mile (23-km) route through narrow tunnels and past needlelike rock formations, including the Needles Eye, a granite spire some 30 to 40 feet (9 to 12 metres) high with a small slit 3 to 4 feet (0.9 to 1.2 metres) wide. The park offers hiking, biking, rock climbing, and horseback riding and has several resorts.
Greenheck is the leading supplier of air movement and control equipment that includes fans, dampers, louvers, kitchen ventilation hoods, and energy recovery and make-up air units. Greenheck equipment is used in all types of commercial, institutional, and industrial buildings in applications from comfort ventilation to manufacturing processes.
Pressure Relief Doors are designed to prevent ductwork from imploding or exploding in the event dampers close while the fan is still operating. The doors permit rapid neutralization of the pressure differential between the inside and outside of the HVAC system.
