Lambert is located near the confluence of the Yellowstone and Missouri rivers near a 75-mile-long irrigated valley. Oil and agriculture are the prominent industries. The nearby town of Sidney is home to the Mon-Dak Heritage Center, which features area history and includes an extensive street scene of the early 1900s. Northeast of Lambert is the Fort Union Trading Post, a National Historic Site, which sits astride the Montana/North Dakota state line.
