Why they call our beach “Singing Sands” 🎶🏖️
Indiana Dunes National Park is home to a rare phenomenon known as "singing sands," where the quartz-rich sand emits a distinctive squeaking or humming sound when walked upon. This unusual acoustic effect occurs due to the sand's high silica content and the uniformity of its grains, which cause them to produce sound under friction. Such singing sands are found in only a few places worldwide, making Indiana Dunes a unique destination for visitors seeking both natural beauty and auditory intrigue. > https://tripmemos.com/budget-friendly-national-park-visits/?utm_medium=organic&utm_source=facebook&utm_campaign=ma
