Near this location is a paleosol collection site in the Jurassic White Throne Member of the Temple Cap Sandstone used by Retallack in his 2009 study of greenhouse crises of the past 300 million years. Retallack used stomatal index data for fossil Ginko and related leaves as a proxy for past CO₂ spikes and paleosol chemical data as proxies for temperature and humidity changes. These data show that global warming due to CO₂ rise is a not a unique event in earth history and that the magnitude of the coming anthropogenic greenhouse pales in comparison with past greenhouse spikes at times of global mass extinctions.
