@RegalBeagle It can have many reasons be it natural if it is near vulcanic activity, meteor or high heat. Another option can be man made if it was near glass production facility. I do not see reason why whould somebody dispose of glass this way when it is pretty easilly recycled
@RegalBeagle I think most likely it was sandy meteor that shattered in the air and hot glassy pebbles hit the ground. Like spray. ☄️ 🤔
