  • Views of the National Parks

    White sand beaches are typically composed of quartzrich sediments. Due to its hardness and chemical structure, quartz is a very durable mineral that is difficult to weather and erode. Therefore, quartz is often the most prevalent mineral found in beach sediments. White sand beaches often include accessory minerals such
