The Niobrara Formation, one such organic-rich shale, is a particularly hot target here in Colorado. While a large volume of natural gas (>700 billion cubic feet by one estimate) has already been produced, it is now Niobrara oil that is the focus of everyone’s attention. Often mentioned for comparison purposes are the Bakken Formation of North ...These tributaries flow over the Rosebud Formation. Some waterfalls drop into the Niobrara, while others are found in spring-fed streams. The Ogallala Aquifer, a fragile, vast underground reservoir, is partially recharged by rainwater and snowmelt.
