  Interesting locations north of Moab
Map drawn August 31, 2009.

There are three interesting localities in this area 13 miles (20 km) north of Moab.

  1. There is a 1913 Marcus E. Jones collection of Frasera paniculata from "Courthouse Wash." From this location, Courthouse Wash descends southeast through Arches National Park, emptying into the Colorado River just north of Moab.
  2. Field Trip Stop 1-1 of Demko, et al., 2005, is at the northern pinch-out of lacustrine sediments of Mesozoic Lake T'oo'dichi'. The sediments are found in the Brushy Basin member of the Morrison Formation (Upper Jurassic).
  3. Just west of the highway are paleosol collection sites in the Morrison and Cedar Mountain Formations 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.
