Title: 
'Clovis' in Color
Original Caption Released with Image: 
Figure 1 This approximate true-color image taken by the Mars Exploration Rover Spirit shows the rock outcrop dubbed "Clovis." The rock was discovered to be softer than other rocks studied so far at Gusev Crater after the rover easily ground a hole into it with its rock abrasion tool. This image was taken by the 750-, 530- and 480-nanometer filters of the rover's panoramic camera on sol 217(August 13, 2004). Elemental Trio Found in 'Clovis' Figure 1 above shows that the interior of the rock dubbed "Clovis" contains higher concentrations of sulfur, bromine and chlorine than basaltic, or volcanic, rocks studied so far at Gusev Crater. The data were taken by the Mars Exploration Rover Spirit's alpha particle X-ray spectrometer after the rover dug into Clovis with its rock abrasion tool. The findings might indicate that this rock was chemically altered, and that fluids once flowed through the rock depositing these elements.
