Mumbai is the city of dreams where thousands of people from across India come to full fill their dreams. Mumbai has some really iconic places but one iconic place has been there which existed even before there was Mumbai, or India or for a matter of fact humanity itself. Gillbert Hill in the Andheri area of Mumbai dates back to 66 million year and is actually a frozen asteroid. Not many know that these asteroids were the catalyst that ended the dinosaur era on earth as the subsequent change in the atmosphere of earth that took place due to these asteroids led to the extinction of dinosaurs from earth.
