Point Lake, Curiosity sol 302
Point Lake, Curiosity sol 302 Point Lake is a dark, massive unit of rock that caps the Shaler sandstone. Members of the Curiosity team have hotly debated whether Point Lake is an igneous rock (a lava flow) or a sedimentary rock (another sandstone, just darker and more erosion-resistant than the Shaler rock).
