A Landmark in History
John Wesley Powell ... The name alone invokes thoughts of adventure, bravery, exploration, and men pitted against nature. Powell expeditions of 1869-1872 on the Green and Colorado Rivers have sparked the imaginations of readers and river runners for more than a hundred years.
Powell's explorations were more than adventures. They provided valuable information about unmapped regions. Powell Point was used as a landmark survey point by the Powell Expedition. Powell Point dominates the landscape, rising 10,188 feet above sea level.

- Retallack, Gregory J., 2009.  

Near this location, just below the summit is a paleosol collection site in the Upper Cretaceous Kaiparowits Formation used by Retallack in his 2009 study of greenhouse crises of the past 300 million years. The location is described as "The Blues." 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.
