This is a discussion thread for the following file:<br><br><b><a href=http://www.googleearthhacks.com/dlfile18137/Heart-Mountain.htm>Heart Mountain</a></b><br><br>Heart Mountain near the Montana-Wyoming border once moved 100 kilometres in a half-hour in a catastrophic scenario during the early Eocene .<br />
The Mountain originally formed with the Absaroka Range, to the West, about 50 million years ago. <br />
However, lava from deep underground slid the mountain to its present position.<br />
The Heart Mountain block slide of northwestern Wyoming and southwestern Montana is one of the largest slides known to have occurred in Earth's history. <br />
The block slide covered an area of over 3400 kmē and moved a minimum of 45 km across open terrain. The initial 2- to 4-km-thick Heart Mountain block slide moved on a slope of about 2°, detaching for half its length on a nondescript bedding plane in the Ordovician Big Horn Dolomite (BHD). <br><br><img src=http://www.googleearthhacks.com/images/new/080505/283904heart.jpg>
