Site types that could be particularly suitable to this survey include desert surfaces, duricrusts, pavements, ice surfaces, and large flat-bottomed canyons.
It's like walking through a canyon.

The continuous line and open squares represents the site at the canyon floor.
The equatorial canyon systems are the only regions in the southern hemisphere where the stability increases.
Birds of prey nest on rock scarps and in canyons that are difficult to access.
Finally, the uppermost area of the painting contains tall, monumental building and canyon-like streets.
