What natural resource is abundant in North Dakota and has been central to its economy?

North Dakota is particularly known for its abundant oil reserves, which have played a crucial role in shaping the state's economy. The discovery of significant oil deposits in the Bakken formation, especially in the 2000s, transformed not only North Dakota's economic landscape but also brought significant national attention to its energy production capabilities. This has led to increased job opportunities, infrastructure development, and overall economic growth within the state.

While coal and natural gas are indeed present in North Dakota, oil has been the standout resource in recent years, driving both local economies and attracting investment. Timber, while available, is not on the same scale as oil extraction and production when considering the overall impact on the state's economy. Therefore, oil is the natural resource that has become central to North Dakota's economic identity.
