This is the visible edge of the Needles Section of Canyonlands National Park. If you want to explore this area further, you will have to walk or go by 4-wheel drive vehicle. The needles are formed by differential weathering caused by erosion due to mechanical abrasion and freezing water in cracks. These sandstone formations are constantly changing, but at a rate that is so slow, that most changes are not visible during a lifetime. It is not unusual to see rocks fall or break away, especially if you spend a lot of time in the sandstone.
