Engineering criteria (latitude, elevation, surface slopes, rock and dust coverage) constrain and dictate to a certain extent where a lander/rover spacecraft can safely land. Scientist must "live" within these guidelines and work to find a geologically interesting landing site. Models of thermal inertia and rock abundance are often used to limit regions for candidate landing sites. However, one must remember that the thermal inertia and rock abundance models are averages and bins are 2 by 2 degree lat, lon and 1 by 1 degree lat, lon, respectively. It is this investigators view that hi-res imagery, of an area in question, should take precedence over models in determining the fitness of landing sites. For instance, numerous hi-res MOC images in the Elysium region exhibit a dust free surface yet the models predict low thermal inertias (fine grained materials/dust). Additionally, there is no evidence for drifts or dunes of fine grained materials in this region of Elysium. The surface in this region has been interpreted to be the result of fluid volcanism, however some interpret this as being the deposit of ice charged mudflows.
