The rock was encountered by the Curiosity rover on the way from Bradbury Landing to Glenelg Intrique in January 2013.[1][2] The rover ran over the rock and broke it. revealing white surface area in the rock.[3] This was the brightest material yet seen by MastCam up to that time.[4]

When the broken white area was analyzed with the rover's MastCam, strong signals of mineral hydration, as indicated by a ratio of near infrared reflectance intensities, were found. According to mission scientists, the mineral hydration signals were consistent with hydrated calcium sulfate[1][2] and a "watery past" on Mars.[5]
