This article was written to document and detail the steps taken in the analysis and evaluation of select surficial objects as captured in images taken by the Mars Exploration Rover Spirit in March 2004. Analysis and research into a specific object began on March 18, 2004 with the web publication of a panorama image of the Bonneville Crater’s edge. The foundation of this paper was begun concurrent with the analysis of images. Formal writing began after 2005 and was supplemented with data and perspectives from scholarly works gained from the landing of Mars Science Laboratory Curiosity. Final updates to rectify an overly terse original were made in 2025. The previously unreleased paper was not intended for publication in any scholarly journal, nor used as a promotional effort for the web site Kilroyonmars.com but, rather as a stand alone effort to be distributed when the time was appropriate. It is assumed that the original un-enhanced version has been seen despite having not been made public.
