Description

This is a short statement that says all the headings in the agreement are for reference purposes only and have no binding effect on the agreement. Mississippi Headings are an interesting geological phenomenon found in the states of Oregon and Washington, primarily along the Columbia River Gorge. These unique erosional features are characterized by steep cliffs or bluffs that abruptly terminate the gentle slope of the Columbia Plateau. The name "Mississippi" is derived from the Missoula floods, which significantly influenced the formation of these headings. Mississippi Headings are formed as a result of the powerful Missoula floods that occurred during the last ice age. Around 15,000 years ago, massive ice dams positioned across the Clark Fork River in present-day Montana would periodically give way, releasing enormous volumes of water. The tremendous floods surged through the Columbia River Gorge, causing immense erosion and shaping the landscape we see today. These floods scoured the Columbia Plateau, cutting deep channels into the basalt bedrock. As the floodwater rushed downstream, it encountered layers of basalt with varying resistance to erosion. The more resistant layers formed ledges or capstones, while the softer layers eroded more rapidly, creating the steep cliffs or bluffs that make up the Mississippi Headings. Due to the varying composition and resistance of the basalt layers, different types of Mississippi Headings can be observed. These variations create a distinct geological pattern along the Columbia River Gorge. Some common types of Mississippi Headings include: 1. Beacon Rock: One of the most iconic examples of Mississippi Headings, Beacon Rock is a towering basalt formation standing at a height of 848 feet (258 meters). It is the core of an ancient volcano that withstood the Missoula floods, resulting in its remarkable prominence. 2. Wind Mountain: Located west of Stevenson, Washington, Wind Mountain showcases another type of Mississippi Heading. It features a basalt bluff that has been eroded on one side, forming a ridge with steep cliffs. 3. Cape Horn: Situated on the Washington side of the Columbia River Gorge, Cape Horn exhibits Mississippi Headings characterized by dramatic exposed cliffs and a prominent basalt headland. It offers breathtaking views of the Gorge and is a popular hiking spot. 4. Hamilton Mountain: Located near Beacon Rock, Hamilton Mountain displays Mississippi Headings with multiple layers of basalt forming terraced cliffs. Hiking trails provide access to the summit, offering panoramic views of the surrounding area. These are just a few examples of the unique Mississippi Headings encountered along the Columbia River Gorge. Their formation and varied characteristics provide an intriguing glimpse into the geological history of the region. Exploring these headings allows visitors to witness the powerful forces of nature and appreciate the remarkable beauty of this natural spectacle.
