There are many places in New Hampshire you can visit to see Geology up close and personal.
Evidence of the Power of Glaciers:
• Most Glaciers in NH were Alpine Glaciers. Next time you ride through the White Mountains, see how many signs you can see of the passage of glaciers. (3:49)
• Tuckerman Ravine is a glacial cirque.
• Polar Caves from boulders off the mountains, dropped by glaciers as they melted.
• Madison Boulder – Largerst Known ‘Glacial Erratic’ in North America.
• Franconia Notch – Carved out by a glacier moving between the mountains.
• Flume Gorge – the sides show differential erosion by glacial meltwater runoff.
• The Basin – A large, swirling Pothole scoured out of the bedrock by glacial melt.
Definition of Pothole – the landform, not the road hazzard.
• Glacial Caves at Loon – (video) Fun to explore.
• Lost River Gorge – More glacial boulder caves.
• The Geologic Wonders of New Hampshire (11:53)
• Old Man of the Mountain (5:08)
• The Day the Old Man Fell (7:45)
Evidence of Volcanic Activity:
• Volcanoes in New Hampshire
• The Ossipee Mountains – are the skeletal remails of a massive volcano.
• This Field Trip Guide – by the NH Geological Society explains Rign Dike formations.
