modified by a wrinkle ridge. NAC M1114391184R, image width is 3.2 km [NASA/GSFC/Arizona State University].</figcaption></figure></p> <p><p>Stratigraphic relationships in today's Featured Image tell a story of complex geologic events on the lunar surface. Planetary geologists interpret images taken from orbit and piece together a narrative. Initially a bolide impacted the lunar surface, creating a crater. Subsequently mare basalt flows buried parts of the impact crater. In the above image you can see darker material around the edges of the crater's rim and also areas where mare basalt material covered parts of the rim and the crater interior. Finally, tectonic deformation created a wrinkle ridge which is better seen in the context image and topography below. Boulders from the wrinkle ridge fell into the impact crater where the edge of the wrinkle ridge intersects with the crater's rim (upper right hand corner of the Featured Image). This impact crater has seen better days! </p> <div class="img-polaroid"> <div class="serendipity_imageComment_img"><a class="serendipity_image_link" href="/news/uploads/LROCiotw/wac_context_annotated.png" onclick="F1 = window.open('/news/uploads/LROCiotw/wac_context_annotated.png','Zoom','height=1140,width=1141,top=157.5,left=717,toolbar=no,menubar=no,location=no,resize=1,resizable=1,scrollbars=yes'); return false;"><img class="serendipity_image_center" src="/news/uploads/LROCiotw/wac_context_annotated.png" /></a></div> <div class="serendipity_imageComment_txt">LROC WAC context image.
