Historic Meets Modern

The historic Upper Musselshell Museum in Harlowton features dinosaur fossils millions of years old, Native American artifacts and stories from the Nez Perce, photographs, historic trains, and more. This museum deserves a connected experience as thorough as its exhibits. That’s why Triangle Communications provides fiber Internet and modern phone services that keep them connected with help always available when they need it.
