In this image from NASA's Curiosity Mars rover looking up the ramp at the northeastern end of "Hidden Valley," a pale outcrop including drilling target "Bonanza King" is at the center of the scene.

Curiosity used its Navigation Camera (Navcam) to capture this northward view during the 709th Martian day, or sol, of the rover's work on Mars (Aug. 4, 2014). At that time, Curiosity was on the sand-covered floor of Hidden Valley. Due to unexpectedly high wheel slippage in the sand, the rover team subsequently decided to drive Curiosity out of the valley, up this ramp, to a higher location for examining a possible alternative route.

The ramp area holds several clusters of pale rocks resembling paving stones up to about the size of dinner plates. The team chose one, dubbed Bonanza King, as a candidate for the mission's fourth drilling into a rock to collect a rock-powder sample for onboard analysis. The candidate target is in the patch of bright rocks between parallel wheel tracks in this image. For scale, the distance between the two tracks is about 9 feet (2.7 meters).

A map showing Hidden Valley is at PIA18408.

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover and the rover's Navcam.
