Kelso Dunes in the Mojave National Preserve are one of the largest (45 square miles) and tallest (700 feet) sand dunes in the North America. They are considered young created in the last 25,000 years by climate change and are often called the 'Singing Dunes' for the booming noise created by sliding sands. Run down a dune and listen for the rumble. A moderate 3 mile round-trip trail takes you to the top of the highest dune and is perfect for solitude seekers.
