Been there wandering around a long time now. I believe this image is from 2005.
This October 9 image taken by NASA's Mars Exploration Rover Opportunity is a portion of a mosaic acquired by the panoramic camera. The picture highlights the light-toned outcrop on the rim of "Erebus Crater" and large, dark, wind-deposited drifts that have filled the center of the crater. The rover is driving west, avoiding the large drifts and crossing the low ripples and outcrop to the right. Image courtesy of NASA/JPL-Caltech/Cornell
