Semonthong Waterfall, Lesotho, Africa Formed: Waterfalls form when a river erodes soft rock more quickly than hard rock and this may lead to the creation of a waterfall. The soft rock erodes more quickly, undercutting the hard rock.
Kayaking along Pictured Rocks National Lakeshore, Upper Peninsula, Michigan. I did this for vacation last year. It's an eight hour day trip along the Pictured Rocks. Breath taking and well worth the money you spend on the experience!
