<dl><dd>The lunar module pilot digs a trench near the ALSEP site at the end of EVA-2. This trench, used for some of the soil-mechanics measurements, was the source of samples 15030, 15040, 15013, and the special environment sample container. At a depth of 30 to 35 cm, the lunar module pilot reported the presence of a hard layer that he could not penetrate with the scoop.</dd></dl>
