New Hampshire Geology
New Hampshire Geology | This is a massive pile of sand deposited by the last continental glacier that blanketed New Hampshire. This sand is 150 feet ABOVE the current Pemigewasset River! That means the glacial river was flowing up in the sky above the sand! Jeepers!
New Hampshire Geology - Lots Going On
New Hampshire geology is best described as a jumbled and tumbled mass of rocks. There are any number of accreted terranes from ancient periods of continental drift and the state is littered with evidence of the last period of continental glaciation. If you are a person that believes in man-caused climate change, you'll not like what you see in New Hampshire.
You should read Rough Hewn Land if you want to discover lots more about accreted terranes. Think of them as enormous thick pieces of ocean bedrock miles thick that resemble wood shavings that are created when a wood plane shaves lumber.
For example, how can you explain this massive pile of sand that's over 150 above the current Pemigewasset River at Exit 23 on Interstate 93? This sand was deposited by a massive meltwater river from the glacier that stretched from the North Pole all the way down to Central Park in New York City as well as all the upper Midwestern states.
Imagine how tall this pile of sand used to be? It's been eroding for over 12,000 years and you know how easily rain causes sand to be transported to the ocean for goodness sake! Keep in mind the glacial river depositing the sand was ABOVE the sand in this photo!
This book is a must-have if you want to discover lots about the world-famous ring dike that we now call the Ossipee Mountains. When you look at a topographic map of these mountains they look like a worn-down volcano. Well that's because they were!
This is the world-famous ring dike we now call the Ossipee Mountains. It was the basement of an ancient volcano. It's quite possibly the only above-ground complete ring dike in the world. And it's in New Hampshire just ten miles from my home.
You'll also tickle your little gray cells as you discover facts about the storied Meredith Porphyritic Granite - perhaps the most beautiful rock in all of New England. The feldspar crystals are large. Some are as big as 3 inches long and over an inch thick. They're so large you've never seen anything like it.
