Scientists are intrigued by the formation. Geologists cite the significance of Purgatory Chasm – Purgatory Conglomerate is their name for it – as an important example of erosion due to wave action and as an illustration of rock compression millions of years ago.{{cite web}}: CS1 maint: numeric names: authors list (link)
