| Some maps show the first 2.5 miles to be Kodachrome Way. | ||
| Road Junction. Some maps also show this little road to Georgetown to be Cottonwood Canyon Road. About 3/4 mile west, where the road starts to climb a small ridge is a collection locality of Frasera paniculata. | ||

Along Cottonwood Canyon Road, about four and five miles south of Cannonville are paleosol collection sites in the Jurassic Carmel Formation 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. | |
