A mantle plume is a proposed mechanism of convection within the Earth's mantle, hypothesized to explain anomalous volcanism. [2] Because the plume head partially melts on reaching shallow depths, a plume is often invoked as the cause of volcanic hotspots, such as Hawaii or Iceland, and large igneous provinces such as the Deccan and Siberian Traps.
Rocky Mountain foothills near Denver, Colorado. Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. [1]
Eagle Plume Mountain (8,724 ft (2,659 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. [3] Eagle Plume Mountain is connected by a gently sloping ridge to Mad Wolf Mountain to the north.
The east side of Mount Baker in 2001. Sherman Crater is the deep depression south of the summit. Mount Baker (Nooksack: Kweq' Smánit; Lushootseed: təqʷubəʔ), [9] also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active [10] glacier-covered andesitic stratovolcano [5] in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States.
The current mantle plume theory is that material and energy from Earth's interior are exchanged with the surface crust in two distinct modes: the predominant, steady state plate tectonic regime driven by upper mantle convection, and a punctuated, intermittently dominant, mantle overturn regime driven by plume convection.

If you want a big dose of energy when you view the front of your home, look no further than a red front door. Lewis says that the color red is a “passionate, amped up” and even “prosperous ...
Although the present topography of the range and adjoining basins is controlled by extension during rifting in the last 10 million years, faults within the range also record deformation during the Laramide orogeny, between 85 and 45 million years ago. The highest peak is North Franklin Peak at 7,192 feet (2,192 m).
