Messier 65 (also known as NGC 3623) is an intermediate spiral galaxy about 35 million light-years away in the constellation Leo, within its highly equatorial southern half. It was discovered by Charles Messier in 1780. With M66 and NGC 3628, it forms the Leo Triplet, a small close group of galaxies.

The thick, layered lava flows of the CRBG erupted as flood basalts, which originate as some of the most highly effusive eruptions in the world. The CRBG sequence a classic example of flood basalt activity that erupted more than 350 lava flows from about 16.7 Ma to 5.5 Ma. The eruptions originated from a series of generally north-northwest-trending linear fissures, ranging from tens to hundreds of kilometers in length, located along the Washington/Oregon/Idaho border. The magma that fed these massive eruptions may have come from a plume-like upwelling from the mantle called a hot spot. Since the time of the CRBG eruptions, the North American plate has moved in a west-southwestwardly motion, and that hot spot is now believed to reside beneath Yellowstone volcano in northwest Wyoming.

The Pacific Northwest is home to more Waterfalls than anywhere else in North America. The Northwest Waterfall Survey was founded in order to create a thorough inventory of these outstanding natural features.

Idaho is a state in the Rocky Mountains of the United States. Idaho is known for its wilderness; there are snow-capped mountains that reach 10,000 to 12,500 feet (3,000 to 3,800 m) above sea level. One of the whitewater rivers runs through the country’s deepest river canyon. Most of the land north of Boise is national forest or state forest.
