Abstract:
The High Resolution Imaging Science Experiment's (HiRISE) imagery of
Mars allows for meter scale identification of surface features. In this
imagery we can identify boulders clustering on polygonal patterned
ground terrains in polar environments on Mars. Previously, terrestrial
analogs of Mars were used to explain boulder clustering. However, the
Mars environment is distinct from Earth's and the boulders that cluster
on Mars are at least 3 - 10 times larger than any found clustering on
terrestrial patterned ground terrains. Here, I propose a new mechanism
for boulder clustering unique to Mars and use observations of boulder
clustering around impact features to place constraints on the timescale
of boulder clustering.
